You have to be out of your freaking mind to confront a shoplifter in a retail establishment these days.
First of all,you are putting your life and health on the line for a store manager that doesn't give a squat if you live or die,depending on how he sees it affecting HIS employment future.
Secondly,there isn't a damn thing in that store to be stolen that belongs to you,AND it is all insured. Hell,these big stores figure "X Amount of dollars" lost due to shoplifting in their budgets.
AND.......,YOU are going to risk YOUR life to try to recover 12 dollars worth of AAA batteries from a shoplifter?
Notify management and let them call the cops.
