Anti-gun violence demonstrators are met by counter-protesters carrying weapons - including an AR-15 - at rally in Phoenix

An estimated 15,000 people participated in March for Our Lives in Phoenix, Arizona. But they were met with a few dozen counter-protesters. Some of these people brought their own guns. The Arizona Department of Public Safety confirmed that no one was arrested during the events on Saturday. Arizona has some of the most lenient gun laws in the country. The state allows its residents to open-carry without needing a license or permit. Pictured are some of the counter-protesters from the rally on Saturday.
