Burglars

"Burglars don't leave their fingerprints at the scene as often as many suppose, because experienced burglars often wear gloves. There are typically many fingerprints, but few of the perpetrators. The responding officer or investigator should make a careful search of likely places, and collect those he can for later screening.""Suspicious activities are:Anyone going door to door. This may be a legitimate business or canvasser, but it may also be a burglar seeking unoccupied homes. Anyone going to the rear of houses. Any loitering stranger. This may be a burglar, drug dealer, or sex offender. Vehicles driving through the area repeatedly. Unexplained occupied parked vehicles. Unfamiliar vehicles backed into a neighbor's garage or carport. This may be a burglar loading up with the household goods, especially if this happens while the occupant isn't home."

This is what Burt said.
