Boeing 757-200 (UPS782)

Departing 30L after a storm passed through San Antonio, moments later I was told by a couple of Landmark Aviation ramp-rats that taking photos of aircraft is against the law due to 9-11, TSA etc., I provided him letters and documents from Airport Police, TSA, ACLU which contridicted what he just said, he then stated "Oh, we called the Police on you". The officer detained me agianst my will even after explaining my right to photography on a public area, a complaint is now filed with the ACLU, fellow photogs stand up for your rights!! Aviation Photography is NOT a crime!
