PHOENIX , Arizona ( CNN ) -- A man toting an assault rifle was among a dozen protesters carrying weapons while demonstrating outside President Obama 's speech to veterans on Monday , but no laws were broken . It was the second instance in recent days in which weapons have been seen near presidential events . A man is shown legally carrying a rifle at a protest against President Obama on Monday in Phoenix , Arizona . Video from the protest in Phoenix , Arizona , shows the man standing with other protesters , with the rifle slung over his right shoulder . Phoenix police said authorities monitored about a dozen people carrying weapons while peacefully demonstrating . `` It was a group interested in exercising the right to bear arms , '' police spokesman Sgt . Andy Hill said . Arizona law has nothing in the books regulating assault rifles , and only requires permits for carrying concealed weapons . So despite the man 's proximity to the president , there were no charges or arrests to be made . Hill said officers explained the law to some people who were upset about the presence of weapons at the protest . Watch the rifle being legally carried at rally » . `` I come from another state where 'open carry ' is legal , but no one does it , so the police do n't really know about it and they harass people , arrest people falsely , '' the man , who was n't identified , said in an interview aired by CNN affiliate KNVX . `` I think that people need to get out and do it more so that they get kind of conditioned to it . '' Gun-toting protesters have demonstrated around the president before . Last week , a man protesting outside Obama 's town hall meeting in New Hampshire had a gun strapped to his thigh . That state also does n't require a license for open carry . U.S. Secret Service spokesman Ed Donovan acknowledged the incidents in New Hampshire and Arizona , but said he was not aware of any other recent events where protesters attended with open weapons . He said there was no indication that anyone had organized the incidents . Asked whether the individuals carrying weapons jeopardized the safety of the president , Donovan said , `` Of course not . '' The individuals would never have gotten in close proximity to the president , regardless of any state laws on openly carrying weapons , he said . A venue is considered a federal site when the Secret Service is protecting the president and weapons are not allowed on a federal site , he added . In both instances , the men carrying weapons were outside the venues where Obama was speaking . `` We pay attention to this obviously ... to someone with a firearm when they open carry even when they are within state law , '' Donovan said . `` We work with our law enforcement counterparts to make sure laws and regulations in their states are enforced .
