Yep. Had the passenger side window busted out in my Silverado, in an appartment lot, while we were having out house built. Ransacked the glove box, never opened the door- because, factory alarm. Probably looking for a gun or cash (I mean what self respecting pickup owner doesn't have a pistol in the glove box?). The only thing of value (my Oakleys) were knocked into the floorboard where the thief couldn't reach them. The person(s) hit about a dozen cars in that lot that night. Same MO. No one heard anything. Glass doesn't make much noise, not enough to hear from inside a building, across a parking lot. And, with those rescue pen spring loaded glass break things being as common as they are, breaking automotive glass is a simple affair.
