Above convenience, it's also just the reality of matters that the shooters in situations like this end up dead every time because they are shooting at people.
Sure, it's very easy to think something is going on with this event, and very well maybe, but at a certain point the logic pattern sails off into outer space.
Except in this case the shooter was shooting at unarmed children and adults - so your comment is idiotic. The shooter decided to off himself per the MSM - how convenient!
