But there is a bigger picture and it involves the inflammatory language used by Trump and many Democrats. After Sayoc, they all need to cool things down.
Trump pushed the envelope at his 2016 rallies by calling on the crowd to take out protestors and he has praised a Congressman who body slammed a reporter.
Trump and Sanders didn’t cause the violence. But now is a good time for the President and the Democrats to make their cases without threat of or praise for physical violence.
