Just after the opening kickoff of the Arizona Cardinals' preseason game against the Dallas Cowboys on Saturday Cardinals season ticket holder John Coulter wanted to take a picture. He says he asked his 15-year-old son to hold his beer cup while he did so.

Seconds later two undercover officers with the Arizona Department of Liquor Licenses and Control approached him. Coulter says they told him that what he did was illegal and that he could be arrested for it. In the end officers escorted the father and son out of the University of Phoenix Stadium.
