Probably, but that's the thing. You don't have to have been caught even once to have driven drunk many times. The problem people IMO are those who get caught once and then a second time. Or more.
It's a tough call. Behavior is unacceptable, but there are urges alcoholics and addicts feel that normal people can't understand. I try to separate judging the behavior from judging the person's character and that it's never too late to turn it around. Too late for consequences, of course, but not for the person.
A friend went to rehab a number of times, was jailed at Bridgewater twice, and I gave up on him. Wondered why he bothered going to rehab the tenth or twelfth time, but that last one took and it was almost 20 years the last time I saw him.
I hope he gets himself straight and I agree with Chris Carter: he's better off on a team than out by himself.
