While I DO NOT agree with the arguement given for this, I have had a serious issue with road blocks like these since I first became aware of them.
We as a society, are supposed to believe in the concept of 'innocent until proven guilty'. Roadblocks are a manifestation of 'guilty until proven innocent'. I object.
If there is a serious crime and felons are known to be on the run in a localized area, I support roadblocks. I do object to roadblocks that are used to troll for violators of DUI, seatbelt laws, registrations and proof of insurance.
Throw the book at DUI operators when they are caught. Leave the rest of us alone.
One of the worst problems with DUI drivers, is that the state and local governments allow them back on the street violation after violation. You don't need roadblocks to end this. Throw them in jail for a year the first time, and DUIs will practically cease.
Second offense, make it five years. End of story...
Perhaps if they put booze stops in surface streets, where the bars are, and invested heavily in busting the sober loonies on highways and freeways, I'd be able to support it.
As of today, I'm not in favor.
What really irks me in this particular link is that they are critcising something I don't agree with for the wrong reasons!
