Easy solution.
Install an automatic gate on the front door, portcullis style. Install a reinforced door in the back of the store. When the mob comes in and starts doing whatever, hit the button to slam the front door closed. Then go in the back and call the police. Sure, they may trash everything. But, since they can't escape, every single one of them goes to jail.
