So can you. Your past experience was terrible, but that's no reason to ignore or misrepresent what others are saying.
What GP and I are both seeing in the Renee video is assault with a deadly weapon on a law enforcement officer. Lethal force is a valid response. That doesn't mean she deserves it, but that she was doing something stupid without realizing just how stupid it was. Most of these protestors are the same, they're new to this and being tricked by anti-ICE activists into thinking it's completely safe without getting all the information.
