The first mistake police officers can make in an encounter with a wheelchair-bound individual is to allow natural compassion to cloud their focus on safety and survival. Some people are in wheelchairs because of criminal activity or violent encounters with the police and may not think twice about injuring or killing a police officer. Police officers should realize not all people in wheelchairs are there permanently and should not assume if they turn their back on the subject he or she will be in the same position when they turn back around. Police officers should also remember some criminals use wheelchairs as a deceptive way of eliciting sympathy and donations, wheelchairs can be very effective for hiding weapons, and even wheelchairs themselves can be serious weapons. On crime-in-progress calls, police officers should not overlook seemingly handicapped individuals who may be acting as lookouts and who may even be suspects. Finally, when approaching a wheelchair, police officers should use the same approach they use when making a traffic stop: approach from behind and remain alert to suspicious hand movements or attempts to hide or retrieve something.
