I don't think anyone pretends it only happens to black people. It is that it disproportionately happens to black people and people of colour. And that black people have a very reasonable fear that police will overreact to anything they do compared to white people.
That is why black people don't always comply. But that is also why people are rightly looking for change given the amount of times this sort of thing happens when someone is complying.
Your whiteaboutery is not helping some of the sensible arguments you might have about how every situation has to be looked at on it merits and evidence.
I was actually highlighting how 'whataboutery' isn't useful, because that's what LL was doing. That was the whole point!
