Chris' escape and Hannah is to blame for everything!
Vincent Hannah literally is responsible for multiple deaths, chaos and disaster because of his approach to this investigation. When the crew leave their botched vault robbery he says 'they will walk away and you will let them!' Siply because it's not a big enough arrest. Well if they had beenarrested the crew would've been broken up, all put under probation supervisin and added understanding of their addresses activities etc, it would've stopped the bank robbery and all those deaths involved in it. Not to mention that if it weren't for Waingro the bank robbery would've gone down perfectly anyway. Hannah is 100% to blame for how disastrous events unfolded, and without Waingro he basically just let a bunch of robbers go loose to get awaywith a massive bank robbery. NOTHING he did in the film actually contributed to the catching of the crew it just fed his insane ego about catching Mccauely himself.
Secondly what the fuck was the deal with Chris driving away? You're telling me the most wanted fugitive in America doesn't have a mugshot they can verify him from? Why would they need Charlene and Charlene alone to identify him? Just arrest him and check him out, check his image against his mugshot? That part of the film is brilliant but so outrageously unrealistic it's absurd. There must have been dozens of criminals low level thugs, cops, etc who could all positively identify him. The idea that only his wife could tell if it was him is ridiculous.
