Selective enforcement is absolutely a miscarriage of justice. Justice is the character of law that makes it fair. If you disagree with this, I would like to hear your defense.
However we can't formally accept that as a society without kicking out one of the main pillars supporting the justice system. If we expect and accept that the justice system to produce unfair outcomes it becomes challenging to justify having court appearances. We could get unfair outcomes much more efficiently by just letting the police and DA arrest whoever with regular internal purges against corruption.
Those laws should never have been used, and if the community wanted to dissuade future productions, they should have passed laws at the city, county, or state level that allows for the proper checks and balances.
