jetta bumpers dont rip off w/o causing serious damage, they use step bolts that have a washer sized head on them, the only way the bumper comes off is either unbolting it, or ripping the shit out of the bolt holes
2 at the top of the bumper “horns”
4 (?) under the grill
2 behind the fog light grills
the grill is also most likely dead too, those are easy to break even while they are still in the box, ripping it free of the bumper is usualy a death sentance
EDIT: check the fiberglass radiator support for cracks also
