“Read here yesterday that the muslim murderers’weapsons were AK-74’s not AK-47’s. The training weapon for muslim terrorists is the AK-74 which by the way is illegal in America. It can only be had on the black market and smuggled into America.”
Bad information. They used AR-15 variants in .223/5.56mm. They did not have AK-74 clones, which are legal and reasonably common in the U.S., in semi-auto variation.
