 Grab your handgun and start firing it up into the air. Shots are going to immediately do a couple of things. It's going to startle the shooter because he's not going to know what's happening. It's going to alert the Secret Service that there's an active threat, and they're not going to have to wonder what you're saying. They're not going to have to interpret. They're going to hear shots and get the president out of there. That's a brilliant idea.
