The nation’s staunchest defender of the Second Amendment has told gun activists in Texas who insist on carrying assault-style rifles in public places to knock it off. In a statement issued late last week, the National Rifle Association (NRA) called out so-called “open carry” groups in Texas that have been frightening restaurant customers and motorists by approaching them while carrying AK-47s and AR-15s. The NRA applauded Texas for a “robust gun culture,” but noted that a number of activists had “crossed the line from enthusiasm to downright foolishness.” “Now we love AR-15s and AKs as much as anybody, and we know that these sorts of semiautomatic carbines are among the most popular, fastest selling firearms in America today,” the statement said.
