It is starting to sound an awful lot like the police chief and others saw this as a great opportunity to further the gun control agenda. What’s a little collateral damage anyway?
I don’t usually consider myself conspiracy oriented but this is acquiring a very ugly smell.
At the conceptual level that's right, but that level is in a different domain than the police chief and his crew. At the operation level it's just the usual - money. School shootings these days are profit operations employing Blackwater-style contractors and corrupt LE. The size of the payoff is proportional to the kid body count. In the aftermath of a school shooting there is a windfall of Federal funding to the locality roughly proportional to body count. When you know it's coming it's easy to get your buckets in place to catch the rain.
This one in particular seems so odd and disjointed, I have to wonder if they went cut-rate and things didn't go as planned. If so we should expect the clean-up to become evident shortly.
