George Zimmerman, who killed an unarmed black teenager, was the guest of honor at a Florida gun show this weekend, continuing his campaign to become the ultimate troll.

The show almost didn't happen, as its original venue cancelled when it found out that George Zimmerman would be there. A gun store called the Arms Room bravely stepped in to host it instead. The show organizers plan to sue the original venue for $300,000, or three George Zimmerman paintings.

Zimmerman signed autographs for the kinds of people who think a man who is famous for nothing more than killing an unarmed 17-year-old should be celebrated. It seems there weren't too many of them: the New York Daily News reported "fewer than 20 people" waited in line to talk to Zimmerman over the course of six hours. Fox 35 reported that there were about 200.

One of them, "Melissa" (who refused to give her last names for some reason), said Zimmerman "seemed nervous and actually a little scared to be there. He also appeared emotional, like he was really thankful and touched that people would come out to see him."

"And wow, he has gained a lot of weight!" she added.

Zimmerman's girlfriend, who once accused him of pointing a gun at her before dropping the charges, was also there.

Zimmerman told Fox 35 that he doesn't understand why people are still so angry at him, "but I'm willing to talk to everyone and try and answer their concerns or questions, and help them realize that there's no need to be angry." He did not propose bringing Trayvon Martin back to life, which is probably the only way to make people not angry.

He added that "of course" he was worried for his safety by appearing in public, but he "couldn't pass up" the opportunity to help the show's organizers and meet his supporters. Also, he is armed and wears a bulletproof vest at all times because "I have to be able to defend myself like any American." So that's great.

Zimmerman would not answer questions about any of his legal issues.
