By black trans man, I assume you’re referring to Tony McDade. The only account of his killing so far has come from the police themselves, who avoid accountability like the plague, so let’s begin by taking that with a massive shaker of salt.
But even if their account is true, the ideal outcome would have been for him to be arrested alive. Why is it too much to ask police to attempt to deescalate the situation before resorting to lethal force?
