We have a right to be armed...at what age? I don't have kids, but if i did i'd make them apologize to these cops and they sure as shit wouldn't be riding around with a wannabe ganagster who has a warrant, drugs, and a gun at the age of 17. The girls would have been fine if they had stepped back and just filmed without saying anything, until they started being tards, then it becomes an officer safety issue and they were secured but not arrested, nor booked.
As far as 2nd Amendment rights i feel like if you're 18 you should be able to buy what you can afford. NFA should be repealed. But there are some people who just shouldn't have guns such as Felons and people convicted of stalking or domestic abuse.
