That's fair. I'm biased to look for an interesting problem to solve but you're probably right that, realistically, money is where I can have the greatest impact.
I want to bail out peaceful protestors but not looters. Is there an organization that is doing some vetting?
Most of the 2020 presidential candidates have posted links. I know for sure Bernie has. If you can trust their team, then that seems like a safe bet.
Police aren't really distinguishing between the two. Besides, even looters don't deserve to stay in jail if they can't afford bail - they'll still see their day in court.
