I didn't mean every interaction, more specifically situations like this where the person seems to be under suspicion of being involved in something dangerous. Typically they'll be told to kneel or lie down, interlace their hands or take other steps to show that they are not a threat. Officers then approach them and pat them down or cuff them till they know whats what. There's always risk but if someone isn't following first instructions the possibility of things going sideways go up exponentially. Every case is different though and we still have little idea what was actually going down here. Hopefully they move quick with releasing the bodycam (not the rioters are likely to care either way).
