Plot hole: In the scene where Jason has his 5th birthday party, after the party it's night time and Bev is sitting on her front step alone when she is startled by her old friend from high school. They begin to walk and talk. She says to him at one point that she is 22. Now when Jason is born, it is stated by her dad that she is 15, so if it is Jason's 5th birthday that would make Bev 20 years old, not 22.
Plot hole: At the end, Pops is cleared of all charges. But the only thing he did was prove Leo lied about some things Pops supposedly did. Its highly unlikely the FBI would drop all the other charges that Pops had really done (illegal gambling, money laundering, etc).
