Get familiar with your state law; not all are make-my-day (or technically, make-my-night) like Texas’. Killing an obstreperous protestor on your property might translate into a sacrifice your family would not want. Won’t do them much good if you’re in a Pennsylvania prison for a few decades.
As for Cornel: The poor of America are much richer than the poor of most other countries. It might suck to go to a dollar store with food stamps and you might wish you never had to darken their door again — but you will NOT starve. Some states will even give you a cell phone. In the meantime, get government’s and unions’ over-burdensome hands OFF of things that can generate more jobs.
If it comes to that they won’t be “protesters”. They’ll be criminals attempting to do you harm. There’s a big difference between protesters and rioters/looters.
