It should be trivial to produce that in a court of law, with substantive actionsble intelligrnce that saying something means it's going to happen.
Except... In reality, horrible people say horrible things on the Internet, all the time, and if we have the Police running around constantly trying to protect one odious group from another, then perhaps it's better to wait until one group substantively commits a prosecutable offense, then deal with them, then.
None of that happened. We went straight to mob justice. Again.
