A black man was hunted down, cornered, and murdered by 3 vigilantes for being suspected of a crime.

Congrats. You managed to find one source that uses a vague word like “mob” but you refuse to acknowledge dozens of other definitions including the very legal definitions of lynching stated in multiple acts and bills.

You’re so hung up on the technicality of one source so that you don’t have to face reality. How many sticks make a bundle? How many birds make a flock? Fuck off. If there’s one thing that’s worse than some pathetic racist piece of shit, it’s a racist who can’t even admit he’s racist.

how lynchings if the past played out

Also not surprising, you don’t know a damn thing about history either.
