Your property is stolen, including a credit card. Your bank calls to tell you that the stolen credit card was just used at a fast food restaurant right down the street. You and a couple of friends head down the street to confront the thieves.
I would argue that, should this happen, you should go down there expecting an armed confrontation. These people didn’t, and the accused thieves opened fire on the would-be detectives.
Go down there to confront them, while your friends who are heavily armed standby with heavy weapons. If the thieves shoot, you overwhelm them with a large volume of return fire (situation permitting, of course).
Before you argue about whether or not you will be prosecuted, remember that if you are really worried about that, you wouldn’t choose to head up there to confront the thieves in the first place. if you DO choose to confront them, don’t hold back.
Expect to see more evidence that people are sick of the cops simply taking a report and then doing nothing. We might as well do away with most police and simply replace them with an online reporting form.
