That's nonsense. BLM exists because there is an enormous appearance that at the hands of police and a great number of the non-black public, the lives of black people don't matter enough to NOT kill unarmed black people for things like playing in a park, selling loose cigarettes, jogging in the 'wrong' neighborhood, sleeping in your own bed, etc.
There has been a significant uptick in all sorts of domestic violence among white people, black people, brown people: all people during this time of economic uncertainty during the pandemic.
Keyword: Appearance. Because BLM isn't about the truth, they take it on faith that if the police shoot a black they were wrong.
We have already shown that police shootings are not racially biased.
