There were 300 extra cops downtown this weekend. You couldn’t go a block without seeing a squad.
Sad it has to be that way, but if that's what it takes for now. Obviously, it's not a workable long-term solution.
Do you remember or know how it was done in Chicago during the sixties? For demonstrations that got out of hand? The cops detained the wilder ones, keeping them in lock-up overnight. Then, most were let go in the norming without charges.
The situation got diffused, the kids got some time to think it through, and they left the station without a record.

Edit: From my reply to you earlier above, I think parental pick-up at the station for the really young ones would work. That's the way iy used to be done back in the neighborhoods with younger kids.
Also, in the lock-up they segregate the detainees by cells. They'll put the kids in their own cell together, away from the other detainees. They don't mix you. That way the kids will be safe, but they'll get a taste of incarceration. I'm speaking of local precinct lock-ups here, not 26th & Cal, just so you know.
In fact when I was a kid the neighborhood cops used to take the kids (early teen boys) down to the local precinct to "see the jail". They'd do this on a Saturday morning, letting you as a group go into an isolated cell at the end of the bloc, closing the cell door behind you so you could "see how it felt". Then, they'd pretend the guy with the keys left for the weekend, and wouldn't be back until Monday! After maybe 20 minutes, they come back and asked you "how it feels", and "wouldn't it be a good thing to stay out of jail"? The idea being, of course, the young boys would learn a lesson not to turn to crime.
In my cops & firemen blue-collar neighborhood, the above visit to the local cop-shop was a childhood rite of passage for the neighborhood boys! No idea if it's still done.
