You guys can do the riot police thing, right? That's what they do when there's thousands of protesters. Maybe set up a roadblock or a barricade or something, I don't know. I mean, it's not like all 500,000 of them are going to be on top of you at once? [He can't even picture that??]

... Sorry, but you're probably gonna have to ask somebody else about this stuff. Just, um, don't kill them.
