you'll remember that shooting. he killed 13 people. he injured dozens more. once again, it's happened here on base. and we know that lopez brought a weapon on to base that was not registered. you can certainly imagine that officials here will be looking into that and how he brought that weapon here on base. >> absolutely. so many questions still to be answered. i know it's really -- you've been there since the middle of the night, but i'm wondering if you're getting any sense from people on the ground there, either on the base or those who live with their families off the base, this is really, like i heard someone describe it, like a city in and of itself, a very tight-knit community. what are they saying, especially considering that they went through this five years ago? >> reporter: it is. it is a city in and of itself. it's a place where many people live. keep in mind, ft. hood is one of the largest, if not the largest military base here in the united states and in the world. a lot of people went through this situation when the base was put on lockdown, when they were told to shelter in place, that they couldn't go outside.
