I bet OP justifies racial profiling too.

This entire movie is a great study in karma and ironic justice.
Teasle and Gault weren't figures of proper justice; rather they were charlatans who used the system to their advantage and were power crazed and hungry. They were awful people who judged others when they weren't anything to sneeze at to begin with. They were two fat, ugly, and past their prime cops who had no other use in life besides to serve the community (badly,) and judge others. Teasle's nothing but a douchebag but Gault's flat out demented in the head.
Teasle was more than likely the douhebag jock in high school while Gault was a bully who loved to beat up people and enjoyed it. They both went to Korea and got out but never got that appreciation for it and it ate them up and they could never get over the trill hence why they were cops. Both especially Gault were jealous as hell of Rambo. Gault wanted to make him his B word by dominating him "You WILL talk to me solider!" while Teasle wanted to ruin his life.
Rambo did nothing wrong in hindsight. He was walking thru the town trying to find some good food and maybe find somewhere to rest and get on his way. He lost his last surviving friend and said friend's wife wasn't the least bit nice or respectful to him. He had a horrendus day and deserved sympathy. But instead the king douche of the Sheriff was awful about it and took it out on him. That was Teasle's grand error he was nothing but a douche during the process and made Rambo want to challenge him. His way to say eff you back was to walk back into the town but he went too early; he should have waited and went back.
Rambo was fate's way of inflicting proper justice on those two guys. Shame the town and the other cops had to be in the way but it happens; that's how fate works. Rambo won, Gault killed himself due to his ego, and Teasle got dominated and hurt for his trouble. Which was what deserved to happen.

99% or Cops know the difference between a tramp and a bum. A bum is looking for houndouts and really doesn't care about himself or others. A tramp is living a transient life and will accept either handouts or work. Many tramps travel til they're out of money, then stay in flophouses and work until they build up a poke, then hit the road again. Rambo is clearly a tramp and would be accorded a measure of respect by the vast majority of LEOs. Most, not all. Some LEOs respect nobody and are the ones deserving of the scorn they get.
I'll share an encounter between a tramp and a Missouri county sheriff I witnessed in 1984, a couple of years after the release of First Blood. The sheriff was alerted one evening by the sheriff's office of the county just to the east about a transient they'd given a lift to the county line, headed into his county now. The sheriff was having a slow night, as usual, so he went to the county line and offered the transient a lift. Yes, he was scoping him out. He made clear to the guy that he was not ordering him to accept the ride, but if he'd like a lift, he could get him to town. The sheriff did not request ID or search him or even ask him his name. The guy accepted the ride (I was along as a civilian) and as we rode back into town we all chatted in friendly fashion. The guy was in his mid-20's and was just traveling the country as a lark for about 2 years. As we approached town the sheriff asked him if he had money to eat on, if he didn't, he'd buy him supper, whatever he wanted. The guy accepted the offer of supper at a local cafe' (it happened to be operated by my aunt), which was provided out of the sheriff's own pocket, not county funds.
During the meal which we all shared sitting together at a table, the sheriff asked him if he would like to stay overnight. The motel could put him up, but it would cost about $20. If he didn't have money, he could let him sleep on the sofa in his outer office. The tramp declined, saying he'd just keep going west. The sheriff offered to give him a lift to the west county line, which the tramp accepted. As we rode west, the sheriff contacted the next county over and said he was dropping a traveling man off at the county line.
End of event as I witnessed it. I'm pretty sure somebody from the next county over met the guy and offered him the same things. There was absolutely no heavy handedness on the part of any LEO in this situation. However, if the guy had been troublesome or out of whack, I'm pretty certain he'd have been dealt with lawfully but with respect.
So in my view, having seen what's possible and probably likely, Teasle was way out of line from the very beginning and the movie flows rather logically as a result. I'd have been pissed off about the treatment, too, if I was Rambo.

Teasel was a douche for doing what he did, all he wanted to do was get something to eat then he was going to be on his way. Why not point out where to eat then help him get out of town afterward if he's so concerned? I like how they all got injured doing the movie.

Rambo wasn't panhandling, he was just walking as I recall. The police can never break the law or do things that they don't have the authority to do. The police aren't supposed to create their own laws and impose fake laws on people just because they want to. Police have to respect and follow the current laws. That's how the law works in the USA.

Infideldog, spoksman for Jerkwater USA.

So a homeless man looking for a decent job is a problem? That makes sense. People are so worried about bums hanging around their towns, so instead of helping them work they decide to throw them out. Why didn't he help the guy? Maybe Rambo could waited tables. Trautman said, "So, it was vagrancy. Wasn't it? Here lies the body of John Rambo, Winner of the Congressional Medal Honor. Killed out of vagrancy in Jerkwater, USA."

If the bum in your story could escape the downtown prison and wage a one-man guerilla battle with the cops, I'd be on his side too.
See you in hell, candy boys!

They move there tents to wherever they can and move along when the city shows up to toss them out. Right now there is a small tent encampment underneath the bridges at 4th Ave. South that lead to I-5 and I-90, next to the home of the Seattle Mariners, Safeco Field. I work at both Safeco Field and Centurylink Field and this group of, say, about 2-3 dozen people moved in about a couple weeks ago.

Seattle? Didn;t they kick all the homeless out of "tent city" about a decade ago? moving them under the freeway or something?
I dont need you to tell me how good my coffee is.

I live in Seattle and this is a realistic portrayal of how small town law enforcement between here and Portland would behave toward somebody who doesn't look like he belongs.
Rambo should have the same to right to be on the land of the fictional town in the movie, but that isn't the way the real world works, unfortunately. He is a citizen who had not done anything wrong, except look like he doesn't belong.

Teasel isn't as bad as Galt but he's still a complete an ass. He's more nuanced and realistic but that doesn't excuse his actions.
If there is a drifter he is breaking the law by harrassing customers or squatting in a place they aren't suppossed to then the police have a right to do something about it. What they DON'T have a right to do is to harass someone just because they decide he's a "bum." It's not illegal to be homeless (in fact, it really sucks and we should feel pity for anyone in that position). It's not illegal to have long hair, dirty cloths, or smell bad. It IS illegal to force someone to leave your town just because you don't like how he looks. Teasel broke the law first and abused his power. He doesn't get to decide who deems worthy of stopping for a bite to eat. I've met a lot of people like him who immediately decide to judge poor people as "trouble."

Teasel was a prick and deserved everything everything Rambo gave back to him and the town.

OP is troll.

Whatever you or anyone else might say, it's against the law to do that. LEO has to make up his mind whether he is a law enforcement officer, or some unwritten rule officer.
.

But to be honest, it's only the first car ride out of town that is the real crime, after that the situation just escalates in a way to a point of no return
No, nearly everything shown from when they meet to when Rambo escapes the jail is blatant illegal use of power by Teasle and his department.
2) Rambo walks back towards town He's refusing to follow a police officers order. Teasle might be an a-hole, but he's still a police officer.
Refusing to follow an officer's order is not in itself illegal if the order violates the suspect's rights. In this case, prohibiting someone from entering public property without legal grounds do so is extremely illegal, like losing your badge and possibly serving prison time kind of illegal.
Stop to think about it. At this point, any police officer; good, bad, corrupted or valiant would probably think, "oh, I think I just did a good job. This guy IS trouble".
That's horrible, corrupted logic. If I randomly run over somebody with my car and it is later revealed that they were planning to rob a bank, it doesn't make me a hero. You can't use hindsight to defend reckless behavior on the grounds that it inadvertently prevented a crime or misdeed from occurring. That isn't doing a good thing. That is using sadistic logic to put a moral spin on a horrible thing. You can't say what a good or valiant cop would do in this situation because a good or valiant police officer would not have unlawfully forced someone out of town. Without cause, there is no effect.
Galt is the biggest prick in the story. While Teasel might behave like an a**hole towards Rambo, at least he does it because he feels it's for the best of his town.
Once again, I will disagree. Galt is employed by Teasle. They are clearly friends. Overlooking his erratic behavior is not in the best interest of his job. By allowing this person on his force, he is enabling the reckless and illegal tactics being used.
What if he'd let him into town, and later that night, two locals were gutted in a bar fight over a flag on a jacket?
That's neither here nor there. Cops are not allowed to enforce law based on who they perceive to be a criminal based on appearance. Furthermore, even if the officer had grounds to believe there was suspicion of a crime, how is it lawful procedure or even good problem-solving to simply throw the suspect over into the next town. If I suspect someone of being a violent criminal, the solution is to let them go commit crimes in another town?

2. Rambo walks back towards town He's refusing to follow a police officers order. Teasle might be an a-hole, but he's still a police officer.
   Rambo has no moral or legal obligation to follow his orders. It is only illegal to knowingly refuse to follow a lawful order, as given by a police officer, and Teasle has no legal power to tell Rambo that he cannot enter the town.
   "No man yet found drinks his tea blacker"

Well, I don't condone the way Teasel handled the situation in general.
But to be honest, it's only the first car ride out of town that is the real crime, after that the situation just escalates in a way to a point of no return

1. Teasel is being an a**hole for driving him out of town, because he can "feel" that Rambo is trouble.
   This is where he went wrong.
2. Rambo walks back towards town He's refusing to follow a police officers order. Teasle might be an a-hole, but he's still a police officer.
3. Rambo is resisting arrest, not violently, but still resisting.
4. Teasle pulls out a huge Knife from the back of Rambos pants, that he uses for "hunting".
   Stop to think about it. At this point, any police officer; good, bad, corrupted or valiant would probably think, "oh, I think I just did a good job. This guy IS trouble".
5. At the station, Rambo is refusing to get his finger prints taken.
6. Galt (not Teasel!) is abusing Rambo in the shower. "clean him up".
7. Galt, Mitch and Ward is going to give the man a shave before court, which trigger torture-flashback and, well, there we go
   Galt is the biggest prick in the story. While Teasel might behave like an ahole towards Rambo, at least he does it because he feels it's for the best of his town. Galt though, is a sadistic prick that physically and mentaly abuses a prisoner, that even his younger colleagues can see "is crazy".
   There is no way that Teasel could've handled point 2-5 in another way than he did It all started with him driving him out of town, which - while being an ahole - was a call he made. Right or wrong.
   What if he'd let him into town, and later that night, two locals were gutted in a bar fight over a flag on a jacket?

I kick a s s for the lord.

So you saw a bunch of hypocritical hipsters (that's why they're hipsters, genius) and that means Teasel is not a complete maniac.
Typical backwater small-town minds.
No wonder you guys (I'm not talking about small-town folks here) are beating up and shooting innocent black people left and right.

I even heard Stallone himself saying once in an interview that Teasle's attitude towards Rambo had nothing to do with Rambo being a vagrant, that it was only "the war of wars" and he was trying to show Rambo that "my war was better than yours".

If it wasn't for the Korean War, we wouldn't have MASH though and that was a great show.

I read somewhere that in the book Teasle is behaving towards Rambo the way he is behaving because he was himself a veteran but of Korean war that didn't get much media or cultural coverage compared to Vietnam war. Nobody speaks about Korean war and yet everyone in the world knows about Vietnam and what a disaster it was. I guess Teasle doesn't like that fact, even though Vietnam veterans got a lot of hate, he's still jealous his war evaded the history spotlight.

only issue is that Rambo wasn't being a nuisance! not doing anything accept walking. he didn't even ask for food, he asked for a place to eat(to which he was told there was a diner 30 miles out of town), then he was tortured FOR WALKING there are no points in this film where rambo is a "nuisance" none. There can be problems with bums being a nuisance, turning around asking everyone that passes for money in places where their presence may hurt the business etc, but none of that applies to the opening scene of first blood. none of it.

Except most people would buy a military man a meal.
