Sssssh! Super-Secret Police Crosswalk Sting Moved From Last Wednesday to Next Wednesday.

Don't get caught doing this at Everglade and Sloat...

A motorcycle officer's sick day forced the cancellation of a Wednesday crosswalk sting operation out in the Parkside -- but not for long. The sting will now take place next Wednesday, April 1.

What's a crosswalk sting? Well, as Capt. Paul Chignell put it in a police bulletin, Plainclothes cops will "attempt to cross the street in crosswalks without being run over by speeding motorists. ... Motorists who fail to yield to these pedestrians will be cited by uniformed police officers." It stands to reason that motorists who run over plainclothes cops are in trouble, too.

The next sting will be 9 a.m. at Everglade Drive and Sloat Boulevard on April 1 -- and here's hoping the saps getting pulled over don't take this for an April Fool's joke.

"People in the neighborhood have been objecting that they can't get across the crosswalk because of the speeding cars on Sloat. Sloat is like a speedway," Chignell explains. "We deal with the most egregious violations. When someone's in the middle of the crosswalk, we've seen drivers swerve around them or start honking. We've seen some unbelievable conduct by San Francisco drivers.

So, gentlemen, start your engines -- at your own peril.
