The decision to arm police like this was not made to protect the public from criminals. It is being done to protect the criminal banking/multi-national/ political establishment (from US citizens) which has robbed the country and the world. To add some perspective to it, being a trash man is more dangerous than being a police officer. It is not a very dangerous job in America. 

Domestically and abroad, I feel like we are in a vortex. If there is no de-escalation all there is is an escalation. With great power comes great responsibility. The true power is in the hands of the state.

As long as we accept that they can use one random exception to set the rule and justify increasing their power, we can never win. All it takes is one person in 300 million for them to justify themselves. And it can be an exception that they promoted or in fact, knowingly caused.
