> I claim that Afroman is a criminal.

At 1:44 his own video (https://www.youtube.com/watch?v=oponIfu5L3Y) says "well, I know why narcotics" regarding the warrant. So I think he'd be OK with that statement of opinion.

If that was defamation, warrants like the one in this case are defamatory, having asserted he kidnapped someone.

The bar for defamation is much higher for public officials like police than it is for private citizens.

Also, while that is a very stupid and racist statement, I don't believe it is defamatory. If you falsely claimed specific crimes, then it might be.
