Of course there should be places and space for actions where people can participate that dont want to riot / be near a riot.
Life isn't a video game. People don't get to choose where they will be when some idiot decides to play hero of the revolution.
Also, the people who were showing up to start trouble were usually police agents or locals who thought that it would be fun to throw a rock at a cop. The IWW people knew more about police violence then you ever will; they were around before Miranda Rights and body cams. If they thought having a team there was a good idea, you should learn from them.
Like I said, it's not the person who throws the brick who gets the consequences, it's someone else. If you have the desire to walk up to a cop and slap them, go ahead. Don't expect other people to get hurt because of you.
