Well actually, if you read my post, I pretty much said exactly that. In absolute terms more white people have been shot dead by the American police, but pro rata, it's more African American and Hispanic folk.
I'm not going into attributing the race blame game regarding crime. What I am saying, however, is that there is a huge problem with the United States police, which urgently needs addressing. Not by defunding, as police are still very much needed, but by root and branch reform of an organisation that is undoubtedly trigger happy - against all individuals. As you say, many white people have also been shot, and many of them, unreasonably.
I return once again to the point I made in my original post regarding the sheer triviality of the reasons for stopping/arresting people, and them subsequently being shot dead. Quite how they escalate so dramatically is a bit of a mystery, but they do. The latest case, post George Floyd, is Rayshard Brooks, who was arrested for going to sleep in his car in a drive thru. Apparently he resisted arrest, grabbed one of the officer's tasers, and was shot dead whilst running off. Again a shooting dead, and two families lives ruined over an incident of everyday banality - you can read the details here
I can't imagine such a thing happening in the UK, either over that, or apparently attempting to pass on a fake $20 bill.
