A month after the start of the great Boxing Day Blizzard of 2010, investigations into the purported sanitation slowdown are starting to slowdown themselves. Because, well, finding evidence of an actual slowdown is turning out to be harder than previously expected.

See, the sexy story of workers not plowing to fight back at the man first hit many media sources via councilman Dan Halloran (R-Queens), who claimed that five sanitation employees, three workers and two supervisors, told him a slowdown had been explicitly ordered to embarrass the mayor. Which is a big deal if true, except the supervisors are denying the story and now Halloran won't say who the workers were (implying that attorney-client privilege also protects him from divulging the names of his clients) and investigators are having a hard time finding anyone else to back up the story (we wonder what happened to that Staten Islander whose best friend told him about the slowdown?).

Halloran has also downplayed his original accusations since they first appeared in the Post on the December 30 (which was days after similar allegations had appeared elsewhere). Originally, he was quoted as saying “they were told to make the mayor pay for the layoffs, the reductions in rank of the supervisors, shrinking the rolls of the rank and file” but now Halloran is saying that nobody was told "explicitly" to slowdown. Halloran is supposed to testify this week before a federal grand jury investigating the mess, so we guess we'll soon know more.

In the meantime, investigators are trying to find actual evidence that workers were intentionally not doing their best. And as much as we wish videos of trucks driving with their plows up counted, they don't—sometimes you just have to pull your plow up.
