Defend the thin blue line...
It comes from two things. Movies/TV and "You aren't allowed to defend yourself".

The reality is anything but.
Cops do not find crimes and solve them.
They don't even try to get people's stuff back.. just send it to auction.
Cops find someone that looks shady, and then harass and torture them till they confess and rat out their buddies. (This only works because there is a large underclass who all have some crime they are hiding)
Half of homicides aren't even investigated.
But, that police is pulling over people for mostly meaningless driving violations.

Police Officers are even worse than the video stated
They are officers, of what? The court.
And the court is the administrative branch of the banks.
So, Police Officers are the enforcement arm of the banks.

Sorry, the police don't work for you.
