Each of the protesters was given the opportunity to write out a complaint, and met personally 1:1 with an officer. Once that was done, the "message delivered", the area needs to be cleared to make room for others without harassment or intimidation from a crowd of disgruntled protesters, and to provide safety in a volatile crowd situation. Yes, indeed, the group should be asked to move to another location to continue their protest. And it was quite hospitable for the police to set up a tent, podium, and provide water. They didn't have to do any of that.
There is no "right" to protest (or harass, or intimidate, or vandalize, or obstruct business, or occupy, or trash) anywhere they wish. A civilized society has laws, rules, and ordinances. Wth all of the recent crowd violence everywhere, security has to be a serious concern. They can exercise their free speech rights, but not illegally assemble or occupy. SCOTUS has affirmed placing limits and restrictions on how, where, and when people can "express themselves". They have been provided a nice space right outside the main entrance. They should use it. IMO.
Sadly, the BLM and other protesters will ruin public perception of this terrible case with their protesting behavior, IMO. This is one of the cases that has serious issues with how it unfolded, and the protesters, IMO, are going to cause the public to lump this case in with the cases of criminals shot by police and protested by BLM. This case is unique. Mr. KInsey is a hero, and deserves at least as much $$ payout as the families of criminals killed who actually fought with officers and took their guns. I hate that BLM is involved with this at all. It cheapens the whole thing, IMO, and casts Mr. Kinsey as one of the common criminals they usually support, which can't be further from the truth.
BLM should sit this one out in deference to the victims, who deserve much more respect than BLM can bring. The protesters are only hurting this case, IMO.
