LAVENDERA: To prepare for this summer's political conventions, Congress is giving the host cities, Denver and St. Paul, Minnesota, $50 million each to pay for security expenses. But what exactly that money is being spent on is top secret here in denver.

NEWMAN: $25 million buys a lot of very interesting things.

LAVENDERA: Bob Newman is an anti-terrorism consultant, helping Denver companies prepare for the Democratic convention. He's anxious to see what kind of crowd control weaponry authorities will deploy for the convention.

NEWMAN: There are also crazy rumors going around.

LAVENDERA: City officials and the police department won't talk about most of the weapons and equipment they're buying.

FLEENER: This is your pepper rounds.

LAVENDERA: But confirmed one report several hundred thousands of high powered pepper ball rifles will be used to disperse crowds.

FLEENER: When that hits, the ball breaks, powder expels. the same reaction as pepper spray. Except it's powder.

LAVENERA: Congressional testimony revealed there will be specialized gas detection equipment and biohazard equipment. Then there are the science fiction-like weapons that may or may not be part of the arsenal, like the goo gun.

SECURITY CONSULTANT: It shoots a rubbery gelatin mass when it strikes the body and comes out in a stream it wraps around limbs and the torso and the person can't move.

LAVENERA: It can make a Humvee have spin in place. Then there are the weapons that would make unruly crowds run for cover like a sonic ray gun, a device which emits an ear piercing sound and a microwave device that can be focused on an area and can make you feel like your skin is on fire. The ACLU has sued the city of Denver to find out if these weapons are in the arsenal.

SILVERSTEIN: Instead of asking the public, "How come you want to know?" Maybe the question should posed to the government, "Why are you interested in keeping this secret?"

NEWMAN: Rational people are not concerned. Those concerned are the ones causing problems.

LAVENDERA: In Minnesota where republicans are holding their convention, the ACLU says it's trying to find out how security money is being spent but law enforcement agencies insist these weapons should be kept secret so they have the upper hand in keeping the convention safe.
