Beijing Olympic plot?

The blurb under this pic from monstersandcritics.com is as follows:

"A policeman stands next to 'Jingjing', one of the mascots for the Olympic Games, at the Auto China 2008 auto show in Beijing, China, 21 April 2008. An estimated 900 cars are to be on display at the exhibition which will officially open to the public from 24 to 28 April and organizers expect to attract over half a million prospective buyers."

So, I'm wondering why one of the mascots for the Olympic Games, is holding a gun?
Are the Chinese planning to repel violent riots, or are they planning to kidnap the world's athletes, hold them for ransom and force the rest of the world to submit to their leadership?
Maybe we should be worried, very worried...
