Here’s a bit of DUI news that we have already seen played out here in the United Sates; police refusing to disclose the location of DUI Checkpoints.

Mexico City vows to punish twitter users who tweet location of police breath test checkpoints

Some Twitter users are revealing the locations of police drunk-driving checkpoints in Mexico City and the people behind the tweets could be prosecuted, police said Monday.

Mexico City Public Safety Department spokesman Julio Iver said it is illegal for anyone to “divulge privileged information on police agencies,” but he did not say what sanctions the Twitter users could face.

Mexico City police change the location of the breath-test checkpoints each day to discourage drunk driving.

So drunk driving checkpoints will “discourage” drunk driving by operating in secret, so that no one finds out.  Hmmm.  Makes sense.
