There’s a Bank Robber in One of 19 Cars in the Intersection

What Would You Do?

There's a bank robber in one of 19 cars at an intersection in Aurora, Colorado. Problem was, the police didn't know exactly which car. So they did something a bit unusual:

Police said they had received what they called a “reliable” tip that the culprit in an armed robbery at a Wells Fargo bank committed earlier was stopped at the red light.
“We didn’t have a description, didn’t know race or gender or anything, so a split-second decision was made to stop all the cars at that intersection, and search for the armed robber,” Aurora police Officer Frank Fania told ABC News.
Officers barricaded the area, halting 19 cars. [...] From there, the police went from car to car, removing the passengers and handcuffing the adults.
“Most of the adults were handcuffed, then were told what was going on and were asked for permission to search the car,” Fania said. “They all granted permission, and once nothing was found in their cars, they were un-handcuffed.”

Even though the police did catch the bank robber, people are now asking whether handcuffing everyone on the spot was a breach of civil rights.
What do you think? Did the police do the right thing? Was it a case of guilty until proven innocent? Or was it a lawful investigative detention?
