Yes, because video lies.
When you add audio to video as has been done in this case, yes, it can lie. The sound of automatic fire has been added to some of these scenes - no automatic weapons were being fired.
Some of the other videos look like training exercises to me.
And at least one is years old and while it does show police doing the wrong thing (and none of those police are on the force anymore) it had nothing to do with COVID.
Some of the others are accurately depicted - but without context - like the police officer who was defending his partner from an assault.
And some do show genuine real incidents- but when they are surrounded by lies, it makes it harder for the truth to be told.
