We need to eliminate the entire police system in this country and reconstruct from scratch.

4. One step up?

I think you give them too much credit, I would sooner trust a member of MS-13 than the cops in this country
But back to the subject, your right,
1. All police forces should be disbanded and re-constituted to reflect what the citizens want and need of their LE officers.
2. All police forces should no longer be wearing military style combat uniforms, they should go back to the pre-combat style uniforms.
3. No more military or military style equipment. No more automatic rifles. Sidearm, semi auto rifles, and shotguns only.
4. No more police depts. investigating themselves, there should be a civillian only investigation agency with no members with any ties to law enforcement.
5. If an LE is found to have committed any crime, whether on or off duty, they are to be immediately terminated and made to stand trial just like any other citizen.

These are just a few suggestions to start with. There are many, many more things that can be done.
