In the past week, for whatever reason, it seems like I've had a ton of conversations about training for Active Shooter / Immediate Response protocols.  The reason?  Just as they always have, bad guys are evolving their tactics.  Some of them are obviously stupid, but the intelligent ones watch and learn and adjust their plans to negate OUR plans or response.  And, just as we (law enforcement) always have, we react to their evolution with our own.  The problem is that means we're always behind the curve. We're always trying to catch up.  Think about that for a second: if you're in a fist fight and you're always trying to react to your opponent's attacks and never becoming proactive with an attack of your own, do you expect to win?  No.  You have to get ahead of his attack and force him to react / defend against you.  We have to have that same mentality when it comes to the next evolution of our Active Shooter / Immediate Response (AS/IR) policies, protocols, tactics and training.
