TIPS ARE GIVEN FOR FOLLOWING SUSPECTS ON FOOT OR IN A VEHICLE, STOPPING SUSPECTS, QUESTIONING SUSPECTS BOTH ON THE STREET AND AT THE POLICE STATION, AND AUGMENTING STREET WORK WITH COMPUTER CHECKS AND OTHER AIDS. ALSO PROVIDED ARE SUGGESTIONS ON DISGUISES, ADOPTING A MANNER WHICH WILL ALLAY THE CRIMINAL'S SUSPICIONS, AND DEVELOPING STREET SENSE.
