The fact that he wasn't actually beaten to death (as likely intended) ends up being a plot point for the epilogue. This is to make sure he can't dispute the apparent facts of the case.
Convenient Coma: Barr is attacked during transport to prison, rendering him comatose. When Reacher takes cover at the quarry, he either chooses large rocks or huge construction vehicles that are more than thick enough to absorb rifle fire. Jack, meanwhile, is realistically (and thus, only temporarily) protected by several stacks of boxes filled with paper, which is a lot more material the bullets need to penetrate. Several Mooks are shot or shot at through solid objects. Chase Scene: Reacher engages in a car chase with Charlie, Emerson, and the police after Reacher finds he is framed for murdering Sandy. Canon Foreigner: All of the shooting victims besides Oline Archer (none were named in the book and she was the only woman killed in the book while here, only one of the victims was a man). Barr selects Reacher's location, naming all the reasons Reacher said he would. Helen asks him to identify where he would've made the shots based on photographs. When Barr wakes up at the end of the movie, he can't remember what happened. Call-Back: Reacher suspects Barr is being set up because the shots were made from a poor vantage point, especially when a significantly better one was close by. The Brute: Jeb, hired muscle meant to intimidate or kill Reacher, played with as he isn't a good fighter or very strong. Oh, and the name of "the auto parts store" turns out to be "Default Auto Parts". He finds her quickly, which wouldn't happen in Real Life Pittsburgh, where most people would think of Advanced Auto Parts, of which there are over a dozen locations in the city and the surrounding area. This becomes a key point, where Reacher wonders which store the girl might be talking about when mentioning "the auto part store". Brand X: While Pittsburgh natives may recognize some landmarks and store locations, all the names have been changed, including the stadiums. Blasting It Out of Their Hands: A lucky shot by Gunny manages to hit Charlie's sniper rifle, disabling it and forcing him to trade in for a standard rifle that will require him to fight Reacher on even terms. This ties nicely into said Big Bad's rants about survival and lifelong prison sentences. Bilingual Bonus: The name of the Big Bad's company, Lebendauer, is just one S short of "Lebensdauer", which is German for "lifespan" or "lifetime". Big Bad: The Zec is the man behind the killings. Battle in the Rain: The final battle takes place in the middle of the rain. Bathroom Brawl: Jack gets attacked by two idiot Mooks with a crowbar and an aluminum baseball bat in a bathroom. #Jack reacher sandy driver
Badass Driver: While Jack has been described as an average to poor driver in the novels, in the film, save for having crashed into a fire hydrant and overshot a turn, he's quite the driver (in which all the stunts were done by Tom Cruise). Reacher: How about the inside of an ambulance?
Both Helen and Reacher believe that Rodin is in bed with Lebendauer because of this, but he turns out to be a Red Herring. Helen Rodin, the DA's own daughter, is pretty sure that many innocent people have ended up in jail or worse as a result and takes the Barr case to fight this.
Amoral Attorney: Alex Rodin, the Pittsburgh District Attorney, got his fame as an undefeated prosecutor because he bullied many criminals into signing confessions without any further investigation or allowing them to see their attorneys first. All Girls Want Bad Boys: When Jack asks Sandy why an intelligent, attractive, and nice teenage girl like her would put up with losers like Jeb Oliver and his crew, she says: "It's what girls like me do." She even hits on Jack again, because she believes he's a bad boy or at least a strong man. In the book, they're more deeply involved in The Zec's crimes, with Jeb killing Oline's husband and Sandy acting as a Honey Trap so Barr won't have an alibi for the murders.
Adaptational Heroism: The worst thing that Jeb and Sandy do is try to have Reacher beat up.
Gunny: Well, you can always start running.
