A friend of mine from Somalia who works as an engineer told me that Mr. Floyd and Mr. Chauvin worked together as security guards in a latino nightclub. So far so true, you can read this also on Wikipedia.
He told me then further Chauvin did this to Mr. Floyd because they made business with drugs and something went wrong. So Floyd had to die.
ALL Demonrat ruled cities have a huge demand for all kinds of drugs. From Marihuana to Crack. So this is also plausible specially if you add the past drug history of Mr. Floyd and the workplace. Nightclubs are known to be locations were drugs were sold and consumed frequently.
He added, because of the looting and arsoning now black people will have it even more difficult. Lots of Somali people live in Minneapolis, so perhaps he has the information from there. I forgot to ask him of his source. He is always very busy on some construction site. Next time I meet him, I will ask him.
I have to add, that in progressive cities corruption of gouvernment employees is a major issue.
