It's the calm before the storm. It appears to us that law enforcement is laying low on the weekend before the amateur's holiday known as the 4th of July, when cops will surely strike down upon thee with great vengeance and furious anger.

This week the LAPD only announced one checkpoint, which went down last night in Koreatown. But that doesn't mean you're off the hook. There are anti-DUI operations running tonight in Malibu, Pasadena and Pico Rivera. Here's the 411:

Tonight from 7:30 p.m. to 3:30 a.m. there will be a checkpoint happening somewhere in the city of Malibu. The L.A. County Sheriff's Department won't say exactly where.

Tonight from 8 p.m. to 3 a.m. Pasadena police will double down with an anti-drunk-driver “saturation patrol” in that fair city. In other words there will be extra cops on the streets looking for drunk drivers. And, in a statement, the department warns that it will have “zero tolerance” for those suspected of DUI. No begging and pleading will get those cuffs off of you, apparently.

Oh, and for your drunk boat operators out there, the sheriff's department has some whoop ass waiting for you too: They'll be cracking down on BUI (yes, it's boating under the influence) at Castaic and Pyramid lakes Friday through Sunday, according to a sheriff's statement.

Many of you comment that we shouldn't be giving up this info, but in most cases local law enforcement agencies want you to know they're out there looking for drunk drivers.

Here's the rational, as explained by the L.A. Sheriff's Department:

The deterrent effect of DUI checkpoints is a proven resource in reducing the number of persons killed and injured in alcohol or drug involved crashes. Research shows that crashes involving alcohol drop by an average of 20 percent when well-publicized checkpoints are conducted often enough.

Mmkay? Be safe.
