My daughter (not shown) played field hockey in Houston this weekend, in the shadow of a tall apartment building. After the Mandalay Bay shooting, I’ve been more aware of large buildings looming over parks and city streets. Of course, there’s not a lot I could do if someone goes all clock tower on me and mine — except recognize the threat ASAP and scurry to safety. Still, I’ve upped my situational awareness. And I [still] don’t do crowds. What, if anything, has been the impact of the LV spree killing on your SA or behaviors?
