It's not nice of him to say it like that, but that's pretty much what everyone knows cops are doing. I don't think anyone expects a different outcome.
One could argue a peaceful protest is different from a riot and cops shouldn't kill peaceful protesters, but there's always a chance they will.
If someone wants zero risk, they can only do short operations that don't need much media coverage to be effective and without a chance for the cops to be present or find them afterwards.
All of those situations can be avoided by them not ordering their officers to show up and harass the protesters. If the cops actually stayed out of the way and allowed them to peacefully protest, there is never a point where anyone should get spit on, hit, or threatened. Then again, if police weren't treating everyone as criminals all the time, it would severely reduce the number of officers they would need.
Partly because of respect, and partly because when you aren't harassing the population, they don't have as many reasons to react.
that's true, but past violent protests with looting and causing damage led to broad calls of regular citizens for police to be there just in case. then, there are those among police who enjoy hurting others and will try to escalate any peaceful protest to a fight.
the only way to end this spiral, would be for protesters to instantly take down rioters among themselves, disperse and go home, so it would become a rare exception for riots to start and police would no longer show up after a few years. but is this realistic? even if some groups manage to do that, others won't. also police could always send instigators who throw the first brick, then leave, so their colleagues have a reason to kill some protesters
the point is to inspire people who don't want to risk their health or want to be more effective to find more effective ways to cause change.
the decision to make it was, that i don't like to watch ppl get hurt and know there are more effective ways, which spoil if one mentions them too publicly. So ppl have to come up with them privately, so the cops can't expect and hurt them.
