Certainly there is a real problem with how this all played out from the actions of the police. We need to review policies and procedures, and figure out where the police actions should have been different. And that will happen, and as these terror hoaxes have become unfortunately more common, new guidelines will be developed. That's not letting the police off the hook-- but it's far too early to eagerly "blame" police for what this lunatic set in motion.
Let's put the real blame squarely where it belongs--on Tyler Raj Barriss, who went out of his way to call in a completely false, highly detailed, shooting and hostage situation. He knew where to call, and what to say, to ensure a robust response. He needs 30-40 years in prison for that, IMO.
Until we learn more about the police response, it's far too early to say what should be done to the officer. I'm pretty certain he's on administrative leave. The evaluation of the police response needs to play out over months, unfortunately.
I'd like to see the penalties for this kind of intentional terroristic false reports be elevated with *substantial* prison time mandatory. These are not "pranks"-- it's terroristic behavior on the part of the one making the false reports. It's not a joke-- it's a serious crime. IMO, just as serious as if Barriss pulled the trigger himself and killed Finch.
