I agree. With your entire post. I take patterns of behavior and project them into future patterns of behavior (I study terrorism) and yes, I can see where you’re coming from. In fact, the model is right there in Great Britain. Remember their Olympic shooting team and the problem they had with “exclusion zones”? Parliament Square, IIRC. And yes, it’ll gain support from a credulous public...it’s ‘for the children’, of course.
Studying terrorism is a hobby that does not suffer from a lack of fresh information.
