Those were paid protests with bad agendas but since they used a common theme that many people would attach to as in demanding police reform, they were able to get extra protesters to tag along with the paid protesters. If it would have been an organic legitimate protest then it may have served a purpose but BLM just used that theme as an excuse to riot, burn, loot, murder, etc.

It was just a theme that they could easily get people to join. The protesters that joined in were actually protesting legitimately but then portions of BLM that were paid to protest along with antifa used a lot of innocent people to take part in those protests to attempt to cover up the actual agenda and it worked for those people here refer to as normies.

We do not need police but if trained properly and better screened before being hired, police could do a lot of good for communities. Unfortunately police have been merely a tool of government to abuse power. That job of being a cop comes with a lot of responsibility which many cops don't seem to give a shit about.
