If she's going to jail for torching a car, then will the officers that committed similar property damage also be going to jail?
It also demonstrates that by and large, police don't prevent chaos and property damage. Most of the time, people simply decide not to do this, and when they decide they want to, police are largely powerless to stop them. This should lead others to more broadly question whether police are capable of stopping other bad actors, rather than merely reacting to them.
