But in all that mess, I'm pretty sure 140-150 of those arrested are truly innocent. The government isn't trusted already - this doesn't help.
Respectfully, the issue isn't just that the vast majority of those arrested are innocent of crimes. The is also the issue that there were wholesale violations of the 1st, 2nd, 4th, 5th and 8th Amendments. Precipitated by suspicious bloodshed and exacerbated by official acts that reinforce an appalling display of careless malfeasance.
I agree with all that, and have remarked about the other issues. The deaths are a big deal, obviously, and as you point out, the lack of justification for arresting innocents is a big deal too.
I think the only point I was making in 91 was that I've been more focused on the unlawful arrests, than on the details of who started the fight, who started the shooting, and who (besides the cops) was involved in use of force that day.
