My answer to 2nd question, What can be done?"
Make it a priority & provide $$$ & resources to law enforcement & prosecutors.
Reuters' Linda So showed us local cops & DAs do NOT make this a priority. It takes skill, time & money.
DOJ's Election Threats Task Force was created to provide resources to prosecute.
They have had successes. BUT THE DON'T PUBLICIZE THEM, so there's no awareness for deterrence for threateners.
Teach:
Death threats are NOT 1st Amdt protected speech!
