I think people are missing the point here because its burried in the article:
"The division had previously cited the Horse & Angel Tavern for over-serving Gabriel Gurule, the driver of the vehicle that crashed into the cab. Toxicology tests showed Gurule's blood-alcohol content was more than twice the legal limit of 0.08 percent. Gurule pleaded no contest in March to three counts of homicide by motor vehicle and one count of great bodily injury."
The bar had also over-served the guy who ultimately killed the other two, I think the cops are just throwing every thing they can at them to make sure something sticks.
No, the two guys in the cab had been drinking at a place called Malarkey's. The drunk driver had been at the Horse and Angel Tavern, which was separately cited.
There are two bars involved -- the one that served the passengers and the one that served the drunk driver. The one that served the drunk driver was rightly cited under the law (though I may disagree with it). They used the same law to cite the bar that served the passengers, though the passengers didn't commit any crime and indeed by taking a cab were avoiding committing a crime by not driving drunk.
I added Texas to the topics because that state is citing people in bars, even hotel bars where they go to their room after drinking in the bar.
