The one where you violated "innocent until proven guilty": "I certainly wouldn't assume the 'open carry' types are automatically innocents".Do you assume police will start shooting anyone carrying a gun?The problem with this is the police had time from the beginning of the march until the shooting started to check out these people carrying in the parade, they were talking and socializing with them, which is unlikely to be the case in the future. So what does one do when no police are around, there are 20 or so people running around with rifles, and shots are fired and people start falling? I certainly wouldn't assume the 'open carry' types are automatically innocents and not doing the shooting.or associated with those doing the shooting, and I can't imagine any of the others would, either, unless they all just happen to know each other, which isn't likely.
Which of my sentences are you referring to? The first is self-explanatory, and so are those that follow. There is a reason militaries like to put uniforms on their soldiers; that way they have a better chance of identifying and distinguishing between their own and the enemy soldiers. How is one going to make those distinctions in a mall or somewhere with no police around and 20 or 30 people carrying weapons around who don't know each other? It's a recipe for some serious screwing up.
FWIW, what percentage of police officers do you assume were there compared to protesters? How long do you think it would take them to "check out these people"? Do you think all people who are exercising their enumerated Constitutional rights should be checked out by the police or do you think only those you don't like or disagree with should be checked out? Please expand on your position regarding American citizens and their Constitutional rights.
