Ah, this shirt. We've seen it on sale in marketplaces far and wide, and every corner of the internet. Never have we seen it put in an appearance in a police mugshot, though. The original intention of it is to be defiant - not everyone who drinks has a drinking problem, and not everyone who's drunk needs to go to rehab. Many people get drunk regularly and go about their normal life.
The place drunks might go when they become a problem - other than meetings and rehab - is a prison. That's where she was when this picture was taken. This is yet another mugshot where the person being pictured wishes they'd worn something - anything - other than the shirt they eventually chose! If she was arrested for an alcohol related offense, it's safe to bet that she was ordered to attend a few meetings because of it. That would turn the shirt into a lie!
