1. I would not use 9-1-1 to call about a pair of losers loitering. That number is for emergencies. I would call the non-emergency number to have these deadbeats removed.
2. These losers should have left immediately as soon as the manager asked them to leave, and they should have left immediately as soon as the police asked them to leave. Private property means something, and they brought the arrest on themselves (I assume that was the plan).
Fair enough. But the result would have been the same. The cops will arrive. Ask them to purchase or move along. They refuse. They asked by cops to leave. They refuse. They get arrested. The call Al Sharpton, the mob, and CNN.
btw.... I have the non-emergency number for my local law enforcement agency in my cell phone contacts. If cell phones were made for anything, they were made for calling the non-emergency line of the cops while you are driving and witness people in cars doing stupid or suspicious things.
The non-emergency line is your friend.
