Not sure where to put this.
I’m from Colorado, but for years before legalization, there were large demonstrations/parties in very conspicuous places (like in a Denver park right between the State Capitol and the City/County building) where everyone smoked openly and the police just stood by and watched. No stress, no violence. I imagine the cops probably loved getting assigned to the event as long as the weather was good. Much better than a Bronco game where they break up a dozen fights and have beer thrown on them.
Where along the spectrum does your state/city lie? Same as Colorado or not a chance?
If five dozen of you got together with the proper permission for using the space, would you get arrested?
College campuses are a special case, so if it’s different in town, let us know. Also, tell us the city/state you’re in.
