You know another thing that has changed is privacy while traveling.

Back in the day taking the train trolly or bus, riding in an open carriage, even stopping for gas where a bunch of attendants would swarm over the vehicle, when one traveled it was almost always under the scrutiny of many eyes.

Nowadays we are in near perfect privacy from our garages to our destination. That makes it much easier for these killers to get geared up to commit maximum damage. Imagine the Newtown killer having to ride the trolly to get to that school. It'd be pretty difficult to hide all that ordinance for very long or carry much ammo for what he weapons he could conceal.
