The justice system is so disgustingly broke that we absolutely need dedicated, level-headed people to do these types of "social hacks" to prove it.
It takes willful acts of civil disobedience to create real change, to bring awareness in a way that's difficult to ignore.
Catching the bad guy is not the only thing that matters in law enforcement, but sadly that's what the militarization of police forces is creating: a system where the ends justify the means. You would not be so dismissive if you were the habitual target of police laziness. It takes a lot of work to catch the bad guys without breaking the rules.
