Despite the Pontiac Bandit's habit of stealing only Pontiacs; a Chevrolet Lumina APV (a rebadged version of the Pontiac Tran Sport) and a Dodge Viper both appear on the bulletin board profile of his transgressions.
Charles says the doctor told him that if the bullet had been 2 mm to the left and a foot higher, he might never have walked again. Charles was shot twice, in each of his butt cheeks, nowhere near his spine. If either of the bullets had hit a foot higher they would have caused significant organ damage but would not have affected his ability to walk.
Charles tells the squad that his doctor said that if the bullet that hit him was a fraction of an inch to the left and two feet higher, it would have hit his brain. He was shot twice, once in each butt cheek. Raising the height of the impact by two feet would hit him in the chest, not the head. Also, neither bullet was near enough to the center of his body to be in line with his head if it hit higher. Although he could have been talking about the fact that he was leaping forward and not standing straight.

Someone with a gunshot wound would have no reason to be wearing a cast, especially a cast that goes up so high.
Gina tells Amy to turn off her phone in the evidence room, even though Gina had already given one item of her preparedness checklist as having a fully charged phone. She ends up live-tweeting the entire experience, alerting Charles to their location. Although she could have meant that Amy should turn off the sound on her phone so that Charles couldn't hear them ringing.
After Jake finds a copy of An American Tail: Fievel Goes West (1991) in Doug Judy's spare bedroom, the two of them begin quoting, "Papa! and "Fievel!" That scene was from the original An American Tail (1986), not the sequel.
