Probably a publicity stunt.
They had to one-up the “Chris Rock gets slapped by Will Smith” fake stunt l they did last year just to get viewers.
Yep - black man is at the height of his career and on television and is arrested.
Entire black community is affected.
They could have arrested him before he went, during the show but waited until the most publicity could be given.
This was intentional to cause more hatred in the black community.
