An offer to buy a strand of hair doesn't suggest assault to me.Legally worse?
AFAIK, offering to pay someone to commit an assault.
But even if someone did pluck a hair off the shoulder of her pantsuit,
to call this "assault" is a stretch.
To hope Trump is assassinated is even more certainly not assault,
but since it might encourage something far deadlier than theft of a
hair. Such encouragement looks worse to me.
And we must remember that the perp in the OP was out of jail on bail.
He wasn't jailed just because of the offer, but largely due to circumstances.
