Let me start by saying I enjoyed this film and thought it was very good.
However, they arrested Alex midway through the film. All they would have to do is interview him/put him on the stand to debunk Aaron/Roy.
A) You should get someone to explain what a "plot-hole" is to you
B) We never see Alex get arrested
C) Who is this "they" you speak of? There are two unattributed pronouns in your last sentence, neither of which makes sense, in the context of your claim.
I don’t understand why Alex told them anything. As far as I recall they didn’t threaten him with anything, and they didn’t torture him. All they did was ‘shove’ him whenever he tries to run 🤣 They’re clearly legit lawyers so they’re not going to beat him up, just tell them to piss off 🤷♂️
It was also weird how they found Alex and seemingly had no plan to make him talk other than chase him through the city, try to corner him somewhere, and ‘shove’ him.
