I find it difficult to understand why a major part of the conversation isn't about how a 13 year old has a gun. It's very casually accepted that it must not have been that difficult for him to get it somewhere.
The situation becomes murky when you take circumstances into account, yes. Difficult neighborhood, unusual time of night, lack of visibility, kid throwing the gun away in the split second he takes to put his arms up, the bias of the officers and self-preservation instinct kicking in, potentially overriding their training, etc. But why did the situation have to be so in he first place?
I'm not taking away from the tragedy of the situation or the complexity of it. It is heartbreaking that an unarmed teenager was shot and died.
I'm just saying, like most non-Americans would, that there's too many guns in America and that's bound to lead to situations like this very often.
Maybe next time the officer remembers this incident and doesn't shoot, but the kid panics and pulls the trigger. Maybe the cops get there too late and a 'good guy with a gun' gets the kid first. A lot of possibile situations, a lot of them resulting in harm, almost all of them negated if there's no fecking guns involved.
