Checked out the thread on this on the Blue Mt. page. Now, I'm all for stringing up the perps from mid-tower of the 6 pack, but from reading the news accounts it seems to me that the folks who got ripped-off may have brought it on themselves.
1) Wouldn't surprise me if they left their valuables in plain sight. Very rarely would anyone looking to steal break into cars randomly and start looking for valuables. Takes too much time. They just want to smash and grab. Working in Center City I see this all the time. People leave a purse/wallet/camera on the seat or the floor and next thing you know the car window is shattered and the stuff is gone.
2) Patrons are warned not to leave their gear unattended or unlocked.
3) Perhaps additional security patrols and/or cams in the parking areas would be a deterent?
If you hide your valuables, use the lockers, leave the expensive stuff at home or keep it with you, there shouldn't be any concern.
