Freedom always comes with responsibility.
Without responsibility there is no true freedom.
For example you are free to drive your car very fast but because of this you can kill or hurt someone else or you can be hurt.
So, if responsibility don't follow freedom, bad things happen.
If people were punished according to damages done by their misuse of freedom, we wouldn't have government problems.
If a person were to drive his car very fast, and he killed someone, he should be executed. If this happened every time, nobody would drive their car too fast.
In addition, police and government make money off people who have done no harm or damage. They make up some laws, and then try to get people to obey the laws. When people don't obey the laws, they fine the people for doing no harm to anyone.
Let the people be free in everything. Make laws to be advisory in nature - no tickets for speeding. But if you do harm or damage by speeding, the same harm or damage is done to you. In addition, you need to pay the other people for the harm or damage you did, at least twice, but maybe 4 times.
Keep the insurance so that the harmed people get their payment. But make the bad guy pay the insurance company back.
This would make things right, and get rid of police brutality.
