I'm torn on this type of thing. For one, this guy obviously a) shouldn't be on the force, or b) at the very least, shouldn't be working in a crowd control environment. He got scared, nervous, and threatened, but (thankfully) didn't actually do anything wrong. Pointing him out as a bad guy is like pointing out some angry protester yelling fits of rage, but doesn't actually do any harm.
Thing that leaves me torn is, you do realize in many other countries the amount of looting and violence that has taken place would have been very minimal, right? So... which is right, which is wrong? You have to realize, majority of residents there are just sitting in there homes, waiting for this to blow over, right? So do you side with the angry mob on the streets and their right to assemble / free speech / so on, or everyone else sitting in their homes waiting for the day they decide it's peaceful to go out at night again?
If the govt wanted to (and what many govts would have done), they would have simply said, "tomorrow 10am, make sure you've evacuated this area". 10am the next morning, they would have blocked the entire area in with APCs, pumped out tear gas like it was machine gun fire, arrested hundreds of people and sent them to FEMA camps for a few weeks / months without charge / trial / family notification, probably killed a few dozen, etc. For the next few weeks, you'd probably see APCs and armed soldiers stationed at intersections & malls, checkpoints all around, etc.
However, 12 hours after that 10am operation started, everything would have been 100% safe and peaceful again.
