“Local law enforcement” means something different in every locality but you are still wrong.
On the contrary, thousands of protestors have been actually charged. Meanwhile police officers are still virtually never charged, even in cases of obvious brutality or obvious murder.
As an example, DA Jackie Lacey hasn’t charged a single one of the 330+ cops that killed LA residents during her 8 year tenure (some orgs say it’s over 600, the police disagree)
