I agree with you OP. People need to STFU with saying all lives matter....that's missing the point.
I really don't think it helps the cause as such and takes away from those trying to raise the matter sensibly
You need to understand this is done out of anger and frustration.
This isn't just about George Floyd...it's about all the other black people who the police have killed and beaten and got away with it.
It's trying to get the attention because the police and the justice system is racist.
This kind of thing triggers people who have also been on the receiving end of police brutality with no recourse....a peaceful demonstration would be ignored.
This is a country who acquited police officers of the horrific beating of Rodney King...there was peace until that verdict was reached....then all he'll broke loose.
I absolutely do not blame them and the focus needs to be on the murder..not the looting.
