And what happens if some 'Black-Lives Matter' people show-up armed or for that matter just anyone of African-American heritage? Or Hispanic for that matter? Or some young men who look like they're from the Middle-East? Are they going to start profiling who will be allowed in with a loaded gun, like you have to be White and wearing a Confederate flag T-shirt or carrying a Bible?
Besides, don't you think the Secret Service is going to have a say in all of this?
If they're not careful, this could be the first nominating convention with a body count.
