I don't know how many folks I gave a ride home or let a friend take them home, rather than arrest them for DWI and ruin their career or life. (Both male and female, but mostly young men) The threat of the reality of that happening was enough that I never had problems with any of them again.
Just because it can result in an arrest doesn't mean it SHOULD every single time.
I had a hard time writing a ticket when a warning would serve the situation just as well too...
The case as presented was a prime example where officer discretion would have had a positive effect.
Money probably swapped hands for the drunks to get a pass.
