What think about Charles Barkley?

It's pretty much pointless. All it does is say to the public that he was sent there. As far as any kind of rehabilitation or alcohol counseling, it's pointless. The only person who cam make Charles stop drinking and driving is Charles attending AA or something, not 3 days in jail.

To show that he is a common man, that he doesn't think that his celebrity should automatically prevent him from a normal person's punishment. 9 out of 10 DUIs or DWIs are handled with probation, so most never see jail time in the first place, unless there are repeat offenders. Most celebrities that commit far more heinous crimes haven't suffered a fifth of the "punishment" that Barkley is doing. So yeah, it might be a publicity stunt, but give the man credit for being a man, and not an uppity celebrity who believes himself to be above the law, he deserves that.
