From AZ Central:

A man who works as a director at the prestigious Barrow Neurological Institute in Phoenix was arrested Friday after he carried a rifle into Sky Harbor International Airport, Phoenix police said.

Peter Steinmetz, 54, of Tempe, was booked into a Maricopa County jail on suspicion of two counts of disorderly conduct for displaying a deadly weapon.

The counts stem from when Steinmetz removed the AR-15 from his shoulder and the muzzle faced toward a woman and her daughter in a waiting area in Terminal 4, according to police. Both the woman and her daughter reported fearing for their safety, police said.

Steinmetz says he only stopped at the airport to “buy a cup of coffee.” And, rather than CCW like anybody else might, I suppose he felt the need to wave an AR-15 around.
