I'm not sure I understand all I've read in this thread.

So you're opposed to checkpoints, but you want the bad guys off the street, but you don't want anything that will inconvenience
you! You want stiff penalties for drunk drivers, but make sure they're caught by some undefined method that
you think will work.
And I always love the comments about "entrapment" since it's nearly always a safe bet that the person making the comment hasn't the fainted idea of the legal definition of that term.
As a teenager I was often out late at night. And before joining the police department myself 42 years ago, I used to work a night shift for 3 years, sometimes got off early, so was out on the streets late at night. I have no idea how many times I was stopped by officers who asked to see my drivers license, asked what I was doing out at that time, where I was going, etc. You know I just answered their questions. I was polite and courteous to them, and they were the same to me. And yep, lots of the teenagers complained of being stopped, having their cars searched, being spoken to impolitely, etc. Hmm, wonder why their cars were searched and mine never was.

And yep, back then, and even after I joined the police department, any officer could stop any driver any time for no other reason than to ask to see that driver's drivers license. Officers didn't have follow all the rules and plans Dan mentioned back then like they do now, and of course the roads were safer back then.
As for the stiff penalties for drunk drivers, in Texas the second offense can be a felony that gets the drunk driver time in the state penitentiary, but it ain't likely to happen unless that driver is involved in a fatal, or at least very serious, accident. I can remember one drunk driver that I arrested and found that he had 6 previous convictions; must have had a good lawyer because he got off for a $700 fine each time. Another drunk driver that I arrested twice myself, sat in jail 8 months awaiting trial because he couldn't make bail. When he finally came to trial, he was convicted of a felony, sentenced to 8 months in the penitentiary by the judge, given credit for the time he'd served, and sent home.
