They need a 30 round magazine
What if you are hunting and come upon a herd of Grizzly Bears?
No...if you own a store and are in the middle of a democrat, black lives matter riot when they are burning and looting everyone elses store...but not yours....because they see you have a rifle with a 30 round magazine..
No....if you are a rancher on the border and you have drug cartels and other coyotes moving across your land and the police are an hour away.....your AR-15 and your 30 round magazine may be your only lifeline...considering the drug cartels arme their people with fully automatic, military rifles.....
No.....if you are in the middle of the aftermath of a hurricane or other natural disaster and the police can't be everywhere all the time....your AR-15 and your 30 round magazine may be the only thing between your family and the thugs roaming the wreckage....
So no....you are wrong.....
