Q: Can people really make a citizen's arrest, or is that an urban legend?
A: People can make a citizen's arrest, but it's not encouraged because of the risk of injury or litigation.
"A citizen may arrest another person for a crime committed or attempted," Seattle police spokesman Jeff Kappel said. "But you must have probable cause to believe the person did the crime."
There are several dangers with performing a citizen's arrest.
How do you restrain someone you've apprehended? How do you call for help once you've done so? Is it clear to the person you're arresting that you're making a citizen's arrest and not assaulting them? And if the suspect becomes violent, how will you protect yourself?
Police operate under what officers call the color of law. Patrol officers have a uniform and car. Detectives still carry a badge and identification card.
Officers go through hours of training, wear bulletproof vests and are armed. Even if a citizen does have some of those three components, officers at several departments believe things will be more difficult for someone who is not a sworn member of a police force.
"We appreciate people's good intentions, but we'd rather you be a good witness," Kappel said. "Walk us to the problem, and we'll take care of it."
