Here is perfect example why employees should never chase crooks.
Supposed a robber stole something in the store, and an employee saw that crook and chased that crook, then the crook runs past me, and I happen to be in straight between that crook and an employee, the crook turns around and fired gun at me instead of the employee. I got injured because of that... I will have no problem dial a number to an attorney, and have that attorney deal the rest... That would mean I will sue the company where that same employee works at, what would I charge? I would press charge against that company for allowing untrained (remember that word untrained) employee, in other word amateur police. And I will be 99% certainly walk off the court with nice sum of money.
That is why most stores and banks don't want that kind of losses.
So, therefore America is truly sue happy country. Sad, isn't it?
