I see a business opportunity for ex-servicemen, especially those with Infantry experience.
They could teach tactics such as "tourists on line", "tourists in echelon left or echelon right", "tourists on perimeter defense" and so forth.
Get some crew served weapons carried innocuously in baby carriages or whatnot bringing up the rear and we could have secret anti-terrorist cells on every tour bus plying the highways of Europe and elsewhere.
Terrorist wouldn't be able to get out "allahu..." before being met with a team of grey haired ladies advancing on him using fire and maneuver.
I think the Israelis already teach this in grade school, don't they?
