The U.N. is seeking to investigate the ICE agent murdering a citizen though

That's because Renee Good committed suicide by federal agent. Charlie Kirk, on the other hand, was murdered by a radicalized leftists . . . actually that assassin and Renee Good have that in common. Both are/were trained activists.

I don’t remember the ICE crawling on a roof an sniping anyone and then sneaking away to his trans lovers house afterwords either, if that gives you some comfort.

AND they took DOWN 48 of em !

Worst case he'll be getting a presidential pardon, put a cube of that ICE in your cup and drink it.
