Ex Illinois Congressman and conservative talk show host, Joe Walsh, sent a threatening tweet the night of the Dallas police killing. "This is now war. Watch out Obama. Watch out black lives matter punks. Real America is coming at you." This is a direct threat to Pres. Obama, not to mention hate mongering. And he is threatening Black Lives Matter supporters. Since he has a radio show, he is able to reach thousands of people and able to inspire someone to do harm to the President. Why has he not been arrested already? Or at least questioned.
