Mayor Michael Bloomberg angrily defended the NYPD’s decision to lock the doors of an uptown D train Saturday so police could arrest Jerry Sanchez, the alleged subway stabber.

 

“If you open all the doors and let everyone run in every direction, you would have the murderer back on the street and I don’t think that’s what anybody wants,” said Bloomberg, his face reddening as he answered reporters’ questions on the topic.

 

Police Commissioner Ray Kelly said he empathizes with the 30 passengers who were briefly trapped in the subway car with Sanchez.

 

“It’s got to be a very harrowing experience, but I think the police’s response was totally appropriate,” Kelly said.

“The cops met them at the station and opened one door, so they could arrest him,” Bloomberg said. “What more could they do?”
