I live in Atlanta, GA, USA.
I had my car stolen. Police didn't investigate.
It was found abandoned 2 weeks later.
Police didn't do anything beyond return it. I figured you had to be shot to get some attention.
Three friends have had their house robbed. No police response beyond insurance paperwork.
Later, a friend of mine was shot.
Police didn't investigate. He was told that he didn't die, so it wasn't murder, so they had more important things to do.
Unfortunately the authorities seem to have too much to do. If it takes any effort to investigate something, it isn't going to happen.
parts of the Twin Cities (Plymouth) are like this for any car related theft. They give you a case number over the phone and that is the end of it. Had my car broken into twice in a parking garage with cameras. No investigation even though about 20 cars were hit each time.
