More than thirty police officers witnessed a collision today. But, this one was planned as part of a training mission. Whenever you have an accident, you expect officers to be able to look and tell what happened. Today, officers crashed a car to learn a lesson. Police officers stood around like they were waiting for an accident to happen.

Training officers from Florida set the scene -- one car about fifty yards from another and both headed for destruction. The class is a constructive crash course with University of Tulsa students, checking measurements and speed of what is about to happen before their eyes.

"We're trying to teach them to work backward to figure out the behavior that went wrong so they can enforce the traffic laws and prevent traffic crashes," says Instructor Keith Rodaway.

For the officers, it's math -- Geometry and trigonometry. Not easy.

"It's not that simple. It's just like a forensic crime scene."

"Certain parts of it are easy," says Broken Arrow Officer Michaela Rott. "But, when you go in to doing your math formulas, trying to determine kinetic energy, speed formula, stuff like that, it can get kind of difficult."

The officers will take this six-week course to become advanced crash investigators. The next step is to crack down on the drivers who go too fast or don't pay enough attention, leading to crashes like the one they saw today.

Officers say when you have an accident, as tempting as it may be, don't bother anything associated with the crash. That will help them conduct a flawless investigation.
