S4·E15 False Witness

While stealing cars for a chop shop, Jose (Joey) encounters Gary, who is brought in by police to ID the teenager in a criminal lineup. When Gary realizes that Joey is Miguel's little brother, he denies knowing him in order to protect his friend. Although Joey promises Gary that he will go straight, his accomplice pressures him into pulling another job, a heist in which the owner of the car is shot and Gary is taken hostage. While trying to convince Joey to give up his life of crime, Gary is wounded by gunfire and left to ponder whether or not he should have acknowledged Joey's involvement the first time around before people were seriously hurt.
