Correct. But they also have to (should) abide by the law. The best recourse (short of getting themselves arrested) would have been a civil (discrimination) suit against the company / manager, as well as media attention. Although, I guess forcing the arrest escalates media attention, but it puts the police in a bad position - they're damned if they do and damned if they don't. I imagine to these guys it was worth getting arrested to highlight the issue. Which is fine too. I'm glad their protest was peaceful, even while being arrested, and everyone is here to discuss how to improve and move forward.
