NEW YORK - Mayor Michael Bloomberg says that police were right in keeping subway doors closed while they searched for a man accused of killing, even though passengers were stuck in a car with the suspect.

Dwight Johnson was stabbed to death Saturday morning in front of horrified passengers on a "D" train. A passenger pulled the emergency chord and police met the train down the line. One door was opened as officers quickly worked through the train to locate the suspect, Gerardo Sanchez, who was arrested.

"Letting everybody run in every direction and have a murderer back on the streets doesn't make a lot of sense to me," Bloomberg said.
