Arrested For Public Intoxication – Inside a Bar?

Irving, TX police partnered recently with the Texas Alcoholic Beverage Commission (TABC) in an attempt to reduce drunken driving. Did they pull people over leaving the bar? No. They partied with them in clubs and after doling out field sobriety tests (in the club); they made arrests (in the club). NBC5I.com reports:

The Texas Alcoholic Beverage Commission has taken its fight against drunken driving to a new level. TABC agents, along with Irving police, targeted 36 bars and clubs Friday, arresting some allegedly intoxicated patrons before they departed the businesses.

Has something changed recently that made a private business public domain? I looked up the penal code for public intoxication and found that public is defined as:

(40) “Public place” means any place to which the public or a substantial group of the public has access and includes, but is not limited to, streets, highways, and the common areas of schools, hospitals, apartment houses, office buildings, transport facilities, and shops.

One definition of public intoxication is: A person commits the crime of public intoxication if he appears in a public place under the influence of alcohol, narcotics or other drug to the degree that he endangers himself or another person or property, or by boisterous and offensive conduct annoys another person in his vicinity.
The details of the arrests are not public at this moment, but experience tells me that clubs have bouncers to handle bad drunks. Experience tells me that some people drink a little more because they have a friend driving. The legal intoxication limit in the state of Texas is .08. That is slightly more than one drink an hour for my body type. Makes you wonder if they are trying to bring back alcohol prohibition.
I am late for a dinner reservation and I do not think that I will be drinking soda with my steak. If you guys don’t hear from me, call the Dallas area jails. I may have been arrested for PI in a private business.
