Wile I don't think they deserved to loose their lives over it, calling them "innocent" is quite dishonest. They were at the very least intentionally being a nuisance and in most cases breaking actual laws in the process.
Pretti was breaking zero laws. You’d have to do some prosecutorial voodoo to conjure up a misdemeanor.
There is lawbreaking in that videos. But the felony-level stuff is all from folks in uniform. (Which, thankfully, they’ve started wearing.)
You're not actually arguing that American citizens shouldn't be able to film the cops are you? That would be pretty un-American.
