I live very very close to where the shooting happened and recently lived next to where CK's gang members lived and held everyone in terror - my DC and friends were working hard to avoid them.
It is 100% right that the police are held to account and act according to the law. Whatever the gang and crime situation, the whole point of a justice system and the rule of law is that it is not the wild west and any suspected criminal activity is dealt with within the law and respects the rights of everyone.
That day residents were in fear and not going out because the chase and helicopter surveillance and subsequent siege went on for hours.
I have no sympathy for the gang members and associates as such, people say CK had friends and family, just like the police, but where was his care for others' friends and family when a member of his gang shot someone else? When he was (previously) carrying a forearm?
It was, afaik, reported that the car he was driving was being looked for as having been involved in a firearms incident, it was known he had previous firearms conviction and armed associates.
But none of that justifies any unlawful killing by the police
It is even more important in areas like this that the police are 100% trustworthy. The would-be criminals need to have no excuses not to respect them, the community at large need to feel that the police are professional and will keep everyone safe.
I hope the trial is rigorous, fair and evidence based.
