We were at a funeral in the process of putting a loved one to rest and a thief smashed into my car and stole my sister's purse (Yes, we should have known better than to leave valuables in the car in plain sight). The car alarm didn't go off and I'm wondering why?? Does it not detect glass breakage? Or maybe the tint I applied tempered the glass breaking noise thus not activating a sensor? Does the car alarm only work when a door/trunk/hood is open while the car is locked? I'll be asking the service center about this when I go and get my window replaced in a few days. I just picked up the P90D back in September. Either way, we caught him on camera and it's making its way thru the media outlets. A few local TV stations were nice enough to broadcast his face in hopes of capturing thief: CBS FOX ABC Notice in the video the alarm did not go off. Why?!
