i had glass on my rails, when my old mk4 got broken into, but it just worked it's way loose, the glass gets everywhere i was still finding bits a year on
, you say they broke the passenger window, but i would check the drivers door lock, i didn't notice it had been attacked too until a couple of weeks later
.
looked as if they tried to do the old veedub screwdriver trick to get the windows to roll down
b*st*rds. know how you must be feeling mate? not good. hope you get it sorted
