Maybe we*ve been thinking too much about mass destruction re: a dirty bomb and the next attack on us is going to be a huge hostage-taking nightmare instead?
Loading/unloading is probably our most vunerable time. I told my DIL this morning I did not want her to be an alarmist but be aware and look around. Look for people you aren't used to seeing, people sitting in cars without kids etc and if she sees anything concerning to not go in. Better for my grandson to be a few minutes late than a hostage.
