Yeah that SHOULD have been a clue. Why keep the cripple alive? Based upon the story, Soze knew all of the crew. Knew everything about them. So why leave the cripple alive.
Seems out of character based upon Virbil's story to Agent Kuyon or however his name is spelled.

You are aware that
Verbal is Soze
, right?

Why would he deliberately get arrested? He ended up worse off after being arrested and showing his face in front of 50 cops and security cameras.
The point, however, is that he got away, much in the same way that he was able to con the crew of 5 into the suicide mission to take out his rivals + Arturro Marquez

I think he did not actually intend to be arrested that time, though it was not a mistake, just a hazard of the job he had to do.

The one at the pier.

Which arrest?

Agree 100%. He wanted to be arrested at the pier so he could tell them that it was a dope deal. The slip up was one of the Hungarians making it off the boat alive.

I'm pretty sure it was deliberate. He wanted to feed the police the dope deal gone wrong story so they would close the case and not investigate any further.
