I propose all law enforcement wear plain clothes and drive every day civilian cars. It wouldn't be any different then the protesters trying to hide their identity by wearing masks. Law abiding citizens wouldn't have anything to worry about. Law enforcement wouldn't be targeted as much and it would save money on uniforms. I think it would work, but I'm sure some sniveling crybabies will opose
They'd cry "Foul!" because they couldn't see their just desserts headed their way.
