Yes, only the unaccountable extra-judicial, legally immune low education, high domestic violence/divorce “law enforcement officers” should have access. It’s not like they would use it to stalk and surveil people … likes they have been caught doing all over and then get away with performative slaps on the wrist and get hired in the next jurisdiction down.
