Letter of the Law? Intent of the Law?

From the "I'ze ain't bein' punk in drublic!" department:

Reuters picked up the story wherein the Texas Alcoholic Beverage Commission (TABC) has admitted that law enforcement agents are going into bars, and arresting patrons for public intoxication. I haven't read the entire Texas P.I. statute recently (snippet courtesy of the Aggies), but it's hard to imagine that the phrase "in a public place" was intended to apply inside of privately-owned businesses. Another key question, what is the burden of proof for establishing that "the person may endanger the person or another?" In the mean time, drink at home (just don't serve anybody else), and watch the NBC news coverage from the Dallas/Irving area.
