Ignorance is not an excuse for rash decision-making. There are a million ways the police could have acted in accordance with the uncertainty about what type of weapon he had, without gunning him down.
In the state where this took place, there is nothing illegal about openly carrying an assault rifle in a crowded Walmart. The police officer should have taken that fact into account.
It's an argument against open carry of assault rifles and a great argument against the open sale and carry of anything that looks like one.
I agree. But both of these behaviors are currently 100% legal in Ohio. The job of law enforcement must be related in some way to the actual law. Thus, I don't think your dismissal of Toni's questions is justified.
You seem to have a very strange and contradictory definition of what constitutes rash decision making. Decisions are made based on an evaluation of information. The information that a man was holding a gun, ready to fire, in a crowded venue, the right decision is to tell someone to drop it, and if they don't, shoot them.
There is nothing 'rash' about acting on information. 'Rash' is hearing someone knock on your door and immediately opening it only long enough to shoot their face off. Rash is slitting a dog's throat because you feel threatened. Pulling out a gun and shooting a kid as he is running away, or chasing someone because they're wearing a hoodie.
Being ignorant about something like whether a thing is a prop or a weapon, the fault lies on the source of the ignorance. In this case, manufacturers of gun toys.
Your view is not consistent with the fact that "holding a gun, ready to fire, in a crowded venue" is legal in the state of Ohio. I don't agree with that law, but the cop's job is to enforce it.
Also, "shoot them" is not synonymous with "kill them." Ever heard of a taser? How about a warning shot? How about aiming for the legs?
Let's look at the availability of information... the suspect was in a location that sold air guns, which look like real guns, in a state that allows people to openly carry around either one. Nobody appears to be in any kind of danger or panic. Equipped with these facts, the officer should have exercised two kinds of caution: (1) be ready to incapacitate the suspect if he acts in a threatening manner --and no, turning toward the source of a shouting voice while talking on the phone does not count-- or (2)
prepare for the much more likely scenario that this is a false alarm and temper any judgement calls accordingly.
