You may make some enemies as a cop, but bearing the badge has its advantages, too. On 'Rizzoli & Isles' (Mon., 10PM ET on TNT), Jane Rizzoli's mom is sold a lemon, and the detective heads back to the car dealership to set things right.

At first the salesman doesn't budge: "According to the law, we're not responsible for abuse, negligence or accidents once the car leaves our lot," he says.

The law? She flashes her badge and asks to see documentation and titles for all the vehicles. Does he rescind the sale and return Angela's trade-in?
