Often yes but 1 - Usually not easily. 2 - Not legally. 3 - Very few automatic weapons are used in the commission of crime or terrorism within the US. The number would be even lower, probably close to zero, if you only look at converted weapons. 4 - Fewer automatic weapons are used for terrorism in the US then in countries that have far more weapon's restrictions then the US has. That's all reading "more rapidly" as "fully automatic" or "burst fire", or "selective fire". You could more easily (and perhaps even legally) add a "bump stock" or similar device that causes more rapid fire, but at the expense of destroying your accuracy. Simpler and more effective (even for indiscriminate terrorists, much more so if you care about who you hit) to just pull the trigger once for each shot. I assume that the people in this latest attack and the attack in Aurora and the Connecticut school shooting knew a little more than the average person yet they all used these "assault" weapons. If you selectively pick a group of attacks that used these weapons, then they all used these weapons. What a surprise. Many other attacks have used other rifles, or pistols, or shotguns, or bombs. "2 or 3 pistols" - Main downside for the attacker is lower accuracy with a pistol unless your really close. That doesn't mean they don't work for such attacks, witness the two Ft Hood shootings, or the Luby's shooting where one shooter killed 23 people with two pistols. Also the concealability factor would have been a plus for the attacker. Apparently the San Bernadino shooters used pistols as well. Considering the fact that it was an in doors shooting I don't think it would have made a big difference if they didn't have the rifles. For a more dispersed out door situation a hunting rifle might be more effective then what the used. For a close in shooting a shotgun might be more effective. I think use of semi-automatic weapons with a military appearance might be becoming a trend but if so its probably has more to do with the reputation f the weapons or some feeling of toughness or effectiveness because of their appearance than any large difference in weapon effectiveness. If you could really stop them from obtaining such weapons (which would be difficult) they would just use other weapons and be somewhere between almost as effective at killing to more effective depending on the weapon chosen and where and how its used. A weapon like an AR-15 or a semi-auto AK might have a range of effectiveness that is useful, being more effective at long range then a pistol or a shotgun, and possibly slightly more effective at short range then many types of common hunting rifles, but not enough to really make a serious difference. Against unarmed people multiple shooters (or often even one shooter) can create carnage with any modern firearm.They've REFUSED to hear arguments against local laws BANNING them. In a much earlier case they made a decision (allowing a sawed off shotgun ban to stay in effect) they made a decision that would seem to indicate that these weapons would be more likely to be protected (as more military they would be more obvious militia weapons). That was long before there ruling that gun ownership in general is a personal right not somehow a right of the state to have militias. Its likely that at some point another circuit will decide differently then the one the USSC didn't review in this case. If that happens then its more likely the case will be heard by the Supreme Court. In any case no one to my knowledge has ever accused the supreme court of being weapons experts. These are semi-auto rifles, similar to other semi-auto rifles, and similar to semi-auto pistols except that they have a but stock and a longer barrel. Bans against them are based on their appearance rather then their functionality.
