This is another great illustration of why YOU are responsible for your own safety:
76-year-old shoots burglary suspect after finding him hiding in closet
Police "cleared" his home and then left to search the area. Apparently, they didn't do a good enough job and this 76 year old vet had to do the job himself.
If anti-2A folks had their way, then this man could have been easily dead by the time the police came back to tell him they hadn't found the suspect. Do not ever turn your self defense weapons in, ever. When you give that up, then you are at the mercy of your "public servants" and their inability (in this case) to keep you safe.
