Well Candi Lightner, and the group she formed call Mothers Against Drunk Drivers, MADD, were the first group which used the "do it for the children" in order to enact legislation.Laws already existed to arrest drunk drivers at the time, and before that time.
But what she did, was make a standardized test, based on blood alcohol level(BAC), to make it illegal to drive. Not based on your driving ability, or how you were driving, of if you got into an accident. Regardless of one's ability to drive after, say 4 beers.
Shortly later, under the same methodology, the random checkpoints were legislated. That police officers could stop drivers, not based on how they were driving, but randomly, and to test them, and search them against the 4th Amendment(which has never been effectively challenged), randomly for their BAC.
Candi Lightner, and her pretty young blonde haired daughter, have become the model for this type of removal of rights of the People.
"Do it for the children".
You see that same mentality in Law Enforcement's rationale for going after vice. They know that adult human beings should be allowed to consent to any number of things(including prostitution). But they will rationalize their efforts by saying that they are trying to stop "human trafficking" which they have NEVER shown any proof of, or to stop "child prostitution", which rarely ever occurs.
"Do it for the children".
If they could convince middle class housewives, that if they gave up their keys to their homes, that it would insure a better life for their children, they would do it, in a minute.
I would rather trust my chances with at 40 year old, seasoned drunk driver,,, than a 16 year old, or a 65 year old driver.
If cops pulled over little blue haired old ladies, just for being old, can't see over the steering wheel...and gave them a routine field sobriety test...I bet MOST of them would fail.
Yes, I agree, there is no difference between a random checkpoint now, than there was in Germany 70 years ago. Papieren Bitte.
Everyone knows somebody who gets drunk on 1 beer, and everyone knows somebody who can't get drunk after 11 beers.
But, we must "Do it for the children".
