It's a common South African insult, in fact I've heard classmates say it to one another in early high school for dating girls in late middle school. It's a word, people sometimes say it. There's a context. It wasn't a formal accusation. One in thousands of comments, you actually expect perfection from Musk and police?
Let me tell you as someone who has pulled off exactly that in 28 conflicts, as if they were 28 chess matches, I haven't fucked up this whole time. It's fucking impossible in the long term. Narrowest odds imaginable. That's not fucking up at all, much harder than merely winning 28 times in a row, which is already staggering. You have to let us fuck up sometimes, let it go. Someday I'll fuck up. Especially due to manipulation eg a racketeer as a last resort, when arrest was imminent, angled his back to get injured by police, in order to get a lighter sentence by countering the guilt of crime with an accusation of police brutality (SFPD police didn't fall for it, not even close).
The bad guys want us to fuck up, it's not easy to foil them every single time. Saying this is possible implies strict inferiority on the part of the bad guys.
And if you expect perfection from the police, you ought to tell them that next time you call them to come vindicate you. So they know you might yourself accuse them of brutalizing your victimizer.
“It is not the critic who counts, not the one who points out how the strong man stumbled or how the doer of deeds might have done them better. The credit belongs to the man who is actually in the arena, whose face is marred with sweat and dust and blood; who strives valiantly; who errs and comes short again and again; who knows the great enthusiasms, the great devotions, and spends himself in a worthy cause; who, if he wins, knows the triumph of high achievement; and who, if he fails, at least fails while daring greatly, so that his place shall never be with those cold and timid souls who know neither victory nor defeat.”
-- Theodore Roosevelt
