Over 3 years ago in the US: several police officers murdered a black man named George Floyd over him using a counterfeit bill within a local convenience store. They placed him on the ground and at least 2 of them placed their knees on Mr. Floyd, including one officer named Derek Chauvin who placed his knee on the neck of Mr. Floyd.

Chauvin would hold his knee there for over 7 minutes until Mr. Floyd was unresponsive. He was declared dead not even an hour later. The death of Mr. Floyd caused a wave of protests across the nation as a result of his death, and there was a greater emphasis placed on murders done by American Police. This was also essentially back to back with the public's discovery of the murder of Ahmaud Abrey who was killed by a former cop; as well as the murder of Brianna Taylor by cops who went to the wrong house in plain clothes and started shooting.

Simply put, a lot of people don't trust police in the US. Many find that police are often useless in investigations, and the body count that they rack up as alleged professionals is terrifying. This sentiment has only grown over the past several years, and there is an ever growing list of murder done by the police in the US with a very large portion being innocent civilians such as the ones mentioned above.

I hope this helped some.
