Stuff stolen from your car

it's becoming pandemic around here they are breaking windows for the change on the floor somehow they have discovered they can pop your window without triggering the alarm with a piece of porcelin insulator from a spark plug .they just throw a little piece at the window and it implodes without enough vibration to set off the alarm . the government insurance no longer covers contents of any kind if it isn't bolted to the car tough nuggets so they are literally busting windows for pennies .A friend of mine who is a former RCMP sharpshooter has had his vehicle done 3 times in the last year luckily the guns where in the house but one of these times he's gonna end up killing a junkie
