Did New York snow crews sabotage clean-up?

In his bombshell revelations, Halloran told CNN on Friday that three municipal workers told him after Monday's blizzard that supervisors instructed them to take it easy in the midst of the crisis.

"'Don't worry if you miss a couple of streets,'" they said they were told. "'The city doesn't care about us, so don't worry about them.'"

Two other workers, assigned to clear secondary streets, say they were sent to their start points and told to wait for instructions which never came. "They told them, 'We'll get back to you,'" Halloran said. "Six or eight hours later they didn't."

Halloran said deliberate sabotage could help explain why the city was paralyzed for two days, when the previous big storm had been cleaned up in 24 hours
