They still nab a whole lot of people, and not just for drinking and driving. Most of them are, erm, "undocumented workers", who likely can't read the paper to begin with. One of our counties has a zero tolerance policy towards illegals, and they get put on the first boat home.
Just sayin'. There are advantages, too.
And as far as "twittering" about them is concerned, how would that be different from Joe giving Bob a call and saying "Hey, take a different route home!" ? Just a different technology to beat up on, is all this is.
Wonder when the ACLU will check in and sue those papers for not printing the notices in more languages, just to be fair, you see.
