Mayor Bill de Blasio defends right to demonstrate after climate protest arrests

Mayor Bill de Blasio is defending the right to demonstrate after more than 100 people were arrested during a rally in Manhattan Monday. 
Chopper 12 was overhead as climate change protesters blocked roadways and snarled traffic near Wall Street, claiming big business is destroying the earth. 
The mayor said that the First Amendment is more important than traffic. 
He added that since New York City is home to the United Nations, it has a responsibility to allow peaceful protests.
