I'm presently concerned about Violence at the Republican National Convention

IF Trump is encouraging his supporters to hit protesters what is going to happen at the Republican National Convention when he doesn't have enough electoral votes to become the nominee?

Is there going to be violence now at the Republican National Convention because of Trump's statments. Will there be bullying of delegates? Will the delegates feel safe to vote their conscience?

Tall and strong men will likely fight back but what if the delegate is old and in frail health or a woman incapable of defending herself because of age or health or disposition? This could be a real problem where votes could be coerced from people who are threatened by Trump Supporters now.
