Protesters at Friday's "Freedom of Speech" rally outside a Phoenix mosque were met by counterprotesters.
The two groups lined both sides of the street in front of the Islamic Community Center of Phoenix and yelled at each other, with a line of police officers standing in the middle of the street to keep them separated, CNN affiliate KNXV reported.
Jon Ritzheimer, organizer of the rally, is a former Marine, and he has no middle ground when it comes to Islam.
