In all cases when someone is shot dead by the police questions need to be asked. Particularly when that someone is a 12 year old boy.
Has the much vaunted protocol been applied correctly in this case? And I don't just mean the actions of the officers on the ground, but the call handlers - was the information they received relayed to the responders so they had more of a clue as to the scene they were likely to find? ie some kid messing about and not a gang-banger fitting to pop a cap in yo ass.
I would question whether or not protocol has been followed correctly here at all stages of this incident, from the taking of the call to the relaying of information, to the actions of the officers at the scene.
The state has taken the life of someone who in all likelihood did not deserve it (stupidity is not mitigating) so it's only right that it comes under the most exacting scrutiny.
Incidents like these raise questions about procedure and if there's any way it can be made to work better, assuming you are working with individuals of high character to begin with, then it needs re-examining most thoroughly.
I'd not limit our discussion here as delusional excuses, as they're just the sort of ideas that will be examined by a competent investigation into the facts. Dismissing ideas as delusional, even with our abstract talking here, is a bit ...well, a bit lacking all round *shrugs*
Some days I think that we can freely discuss this sort of thing - I mean bitch about and argue over - is something we all take too much for granted.
