The good guys are made out to be evil in this movie and in the book
I don't think an established US Attorney like Foltrigg would be dumb enough to tell a kid that he doesn't need a lawyer on his parent present when he was being questioned. That was one thing I didn't like. That's like a surgeon telling a patient that they don't need anasthetics for the operation.
I also didn't find it believable that an alcoholic woman with only four years experience of law could outlawyer a veteran like Foltrigg. That was B.S. too. Gregory House is a more believable character than Reggie was.
The cops, FBI agents, and prosecutors are all made out to evil in this movie. All that Mark had to do was get a Witness Protection Program deal signed and tell them where the body was and the movie would've been about an hour shorter. Instead we have Mark faking seizures, outsmarting smart people, perforoming identity theft, and obstucting justice. Just wonderful. John Grisham, you suck. Watch and episode of Law and Order and you'll see how to do things right.
