Problem isn't IMO the institution or it's power, it is who gets hired and how impossible it is to predict who will do the wrong things days or years down the line.
The Institution is rotten to the core. The powers abused are rotten to the core. The ability to use traffic stops to generate revenue for the courts is rotten to the core. The use of traffic regulations to circumvent the 4th Amendment is rotten to the core. The militarization of the Police is rotten to the core. The training of Police to circumvent the 4th and 5th Amendments is rotten to the core. The seizure of assets, both cash and otherwise by Law enforcement without due process is rotten to the core. We need a re set. A re-balancing of powers. A new Magna Carta as it were.
So what do you propose? Continuing with the use of the Police to ignore Posse Commentates? Ever more powerful Police and Courts who routinely ignore the Constitution and the Bill of Rights? A surveillance apparatus that makes George Orwell look like an amateur? What do you want besides defending the status quo?
Go to sleep sheep. Everything will be fine.
