McCarthy says students may have the wrong idea about the role of the police in breaking up parties.

"We are not out to bust the students. We are here to help the students," McCarthy says. "We don't go out sniffing for parties and sniffing to bust parties."

Cop's Sixth Sense

Logging so much time behind the wheel of a car allows officers to develop special talents.

Driving without seeming to look at the road ahead is a habit for the men in blue--although it can be quite disturbing for those riding along.

Instead of focusing on the road, their eyes hone in on roadside activity.

"I'm always scanning, looking to see if [I] recognize somebody out of place," McCarthy says.

Crowley says the habits he has developed as a police officer make it difficult to switch to being a civilian.

"My wife yells at me all the time.... She tells me I'm looking everywhere but in front of me," says Crowley, who has been married for two-and-a-half years and is the father of a pair of 17-month old twins.

Crowley says that being able to sense when something is not right comes with experience.

"You get a sixth sense of what's not right," McCarthy says.

Veteran officers, for example, often become adept at spotting stolen cars on a busy highway.

McCarthy says he wows his wife by pointing out stolen vehicles when they are driving.

Crowley says one clue to a stolen car is a missing trunk lock.

McCarthy and Crowley have also developed enhanced hearing as a result of listening to the constant drone of their police radio.
