For the St. Paul cops who arrived at the Super 8 Motel Monday night, the decision had to be made. 36-year old John Carr was suicidal and high on methamphetamine. In the third floor hallway, four officers shot him to death.
St. Paul Police say Carr was well within what's known as a 21-foot danger zone. Joe Dutton, a retired Golden Valley officer and expert in the use of force, showed FOX 9 how quickly a suspect with a knife can reach an officer. He says officers have less than two seconds to react.
The officers at the Super 8 were in a narrow hallway, which limited their options.
“If you don't have an ability to move laterally, you're very much in a tunnel of death situation here."
