I heard the guy this morning. I don't think he's wacky, there's no way to determine who's who and many on the left are filled with hate. He says he's very pro-2nd, he's just worried about a powder keg blowing up on their watch.
Lots of open carry in Dallas caused a lot of confusion and many are dead now.
Not a single person was killed by the people open carrying at the protest (we don't know if the shooter was part of the open carry group or not), and none of them were shot by cops. They did what they should have done, they did not go looking for the guy, or get in the way of the police.
You missed the points, it makes it difficult for the cops to tell good people with guns versus bad people with guns.
Dallas police chief: Open carry makes things confusing during mass shootings
Actually, considering Texas has shall issue concealed carry, they have to assume anyone could be concealed carrying as well. In the end, none of these people got shot, and they didn't shoot anyone, so I doubt the confusion they caused was any greater than the confusion of unarmed people fleeing the area, and of course, the confusion caused by the shooter.
