So, what ideas are out there that you like?
Assuming you had unlimited money to spend...
Focusing on the high incidence of unnecessary deadly force being used against brown and black people by white police officers; what would you do address this problem?
To me, the "deadly force" issue is a symptom of a much bigger problem. On a per capita basis, black people have a much higher incidence of confrontational interactions with police than white people do. While I'm not in denial about racism, I think the most obvious reason for this discrepancy is economic. People (of any color), who are in dire economic straits, are bound to be "in trouble with the law" more frequently than people (of any color), who have some degree of financial security. For example, it's pretty clear to me that if millions of people start getting evicted in the next couple of months, there are going to be a LOT of harsh interactions with the police, and a lot of people of all colors are going to be on the wrong end of these exchanges.
So my idea is that attacking wealth and income inequality will have a far bigger positive impact on black lives than improving the country's police forces will.
