Unions, in general, are full of good people whose leadership is singularly power seeking and often corrupt. Police unions are no different. We honor and appreciate our law enforcement, but understand that every bushel has a few bad apples. Police unions protect the bad apples from accountability, thus throwing the good fruit under the bus. If we want to change this, we need to start protesting union bosses, not the good men and women in blue protecting our lives on a daily basis.
