Reported by USA Today, a master firearms instructor stated, "There are rifles that are more powerful and more dangerous than [the AR-15], but they're not being used." The instructor suggested that shooters perhaps choose the AR-15 because it is the weapon of choice for police and military. But the police "choose it because it is under-powered ... making it less likely to penetrate interior walls and hit an unintended target."[1][2]
