The new program, which Zingo said is the first of its type in the nation, gives rookies the chance to see that most people aren't criminals. Too often their perceptions are shaded from the seat of their patrol cars, which they seldom leave, he said.

"This deployment allows them to have contact with business owners, families out shopping, people going on with their lives," said Capt. Rick Jacobs, commanding officer of the Training Division. For the rookies, it gives them a crash course in crime fighting, community interaction and basic, street-level police work.

Here's an example of how it works:

With her factory-fresh police belt holding revolver, mace, two nightsticks, and one radio, Jeanine Giordano strides into Hollywood Star Market. "Sir, we are just walking a foot beat up and down the street. ... I'm sure you've seen us," says the young police recruit to a Korean working behind displays of beef jerky and pen lighters. "If you have any problems or questions," she adds after a conversation, "go ahead and let us know."

The clerk's nervous frown melts into a broad smile.

Good for Bratton, and good for LA.
