From a comment referring to the Gestapo harassing photographers:

That’s right; I don’t want to be too technical, but the focal length of the lens is directly correlated with hatred of America. It goes something like this:

You have a a cell phone camera, point and shoot, or 20mm wide angle lens: you are a red blooded American who wants to celebrate our national heritage by taking pictures of popular tourist locations.

A 50mm lens: you are also, by and large, a good American, but you have a disturbing interest in “understanding” the terrorists and why they attack us.

An 85mm lens: you loath your own country and secretly admire the 9/11 hijackers for giving us our come-up-ins. You are not a terrorist, but your camera should probably be confiscated and your pictures deleted, lest they find their way to al Jazeera message boards. Your middle name may be Hussein.

A 200mm lens: you are an al Qaeda henchman actively scouting for security vulnerabilities.

A 300mm lens: you ARE bin Laden!

And yes, every tripod is suitable for launching RPGs, but you need a ball head to attach heat seeking missiles.
