I think the fact these attacks are happening regularly all over the world normalizes this already. The odds of you being the victim of a terror attack are low but honestly you don’t need a 15 minute course on tips. Make news distributors run a 2 minute clip on how to effectively maximize your odds of survival during every broadcast coverage of a mass shooting. I think it also changes the narrative in a would be perpetrators mind: if this is about power over others, to some extent others are now prepared to either flee or effectively attack a terrorist en masse.
