Though leaving things out in the semi open in your car is a bad thing that I don't see that being entirely the car owners fault. These guys now use spark plugs to shatter windows cause if they know how to do it right it will not set off a basic alarm. Everyone has something worth value that these thieves can take. Not only that I made a stupid mistake by accidently leaving my car unlocked literally in front of my apt. on the 1st floor and I guess someone had been watching me take groceries out from earlier and saw I did not lock it. Next morning get in my car and things are thrown everywhere cause they were looking for something (nothing to be found though). Just goes to show that there are some very sneaky criminals out there.
