What I find most problematic is how frequently peaceful protestors are being arrested. As far as I can tell, he wasn't lobbing Molotovs at the White House, trying to climb a fence, or otherwise posing the sort of threat that would justify interfering with a peaceful protest. But courts appear to have given large leeway to police to put "time and place" restrictions on protestors, arresting them for e.g. picketing on a sidewalk that falls outside specially approved "free speech zones".
