There are zero reasons that someone should be beaten to death by officers of the peace. This is a normal created by those who rely on the threat of violence for control and is acceptable under law written by those who arm the perpetrators.
The United States was founded on the principle that all men were created equal but operated on the practice that not all people were men. Some could be treated as less than livestock. Doing so made for handsome profits that paid for the system to be further developed.
Memphis was founded as a distribution center for the plantations in the area. MPD was not created to fight crime but to be enforcement for the owners and bosses. Their brutality will not cease until the city changes its fundamental identity to elevate, rather than enslave, humanity. This would make bad profit margins for the area’s largest employers. Moderate whites won’t risk their retirement package for equality. Thoughts and shares is the most any should expect.
It’s a rotten situation started by rotten men under the guise of greatness. Change for a better tomorrow won’t be happening for a few more tomorrows.
