According to this report in Actualic, Arabs from East Jerusalem have been pulling down flags in the French Hill neighborhood from parked cars. Police acted quickly and have arrested 3 people involved.

This tells me one of two things:
1. The police in Jerusalem function far more efficiently, and much more like actual police, than the police in Bet Shemesh
2. The Arabs are just not lucky enough to have been Haredi. For the same crime they would have been ignored.
