So I've had this lung infection for days and while I was tripping on a combination of codeine and pseudoephedrine, I got to thinking. For me at least, it seems clear that as long as projectile based weapons are the premier individual weapon system, they will fall (for the most part) under the right to bear arms. However, it appears as though man portable projectile based weapons systems are approaching their peak. The development of rail guns may expend their peak somewhat, but a newer, more badass form of weapon is being developed. Directed energy weapons. Directed energy weapons are superior to projectile weapons in almost every single way (in theory at least): Much more accurate, speed of light engagement means that you don't have to lead your target at ranges below 50,000 miles and the effect of gravity on DEWs is negligible on earth Recoil is negligible also With a big enough power source, "ammunition" (for lack of a better term) is unlimited Even as technology advances, DEWs will be difficult to counter There are already prototypes of vehicle mounted DEWs but inevitably, as technology advances, a man portable application for them will become available. So when these weapons, which will be much more lethal and easier to use than our current technology, become available, will the 2nd amendment cover these weapons also or will the Federal government pass legislation to restrict them before they become as ubiquitous as semi auto rifles are today. Can't imagine some conservatives being happy that the government has man portable DEWs and the everyman is stuck with a projectile based weapon. You might as well own a bow and arrow if you bring a bullet to a laser fight, right?
