Finding the assassin

You teleport to the Hollywood sign in Los Angeles, since you're not familiar with the city and you need a place that's not so obvious. It's still light outside and you don't want to be seen in your costume, though you suspect you might not stand out that much in Los Angeles.

You check your phone for the latest news on the would-be assassin and it looks like the police has him surrounded in an abandoned warehouse nearby. However, the guy claims to have a bomb strapped to his chest and for the moment, they're just waiting him out. Luckily for you, plenty of people and news crews have gathered at the scene and there are lots of pictures of the warehouse. One person even posts a old picture of the interior of the warehouse from a few years back when it was still in use, which is perfect for you.

You teleport into the warehouse, and it's huge, but also empty except for the guy who tried to kill the vice president, and some crates and stuff. He's dressed in a black shirt and ripped jeans and he's leaning against the wall while peering out a window at the police, so he doesn't notice you when you appear. You can see plainly that while he has a gun, there's are no explosives on him and he's just bluffing to the police. This is your opportunity to be a hero and unveil yourself to the world.
