Protesters at the Denver airport over the weekend were told by police that it was illegal to exercise "free speech without a permit."
Denverite reported that over 200 people gathered at the Denver International Airport on Friday to protest President Donald Trump's executive order banning travel from seven majority-Muslim countries.
"Stop doing anything that could be construed as free speech without a permit," he explains.
Lopez warns in the video, which lacks context, that even carrying a copy of the U.S. Constitution was prohibited in the airport.
"I cannot carry the Constitution without a permit?" one protester asks.
"Correct," the officer replies.
