Until the perpetrators are convicted things are not settled. The charges definitely are justified and a good sign of improvement, but if these guys get off there may be additional retaliation. Also the overall nature of grotesque publicized gang violence under the name of law enforcement seems far more impactful than one disgusting cop with a bunch of standbys in the case of George Floyd. Even if everyone involved gets convicted it's still an unsatisfactory response for most people that are not ok with this behavior
