I often have discussions with pro-gun friends of mine about reasonable solutions that would allow them to retain their weapons, which they evidently greatly favor, and would still increase overall safety. It seems to me that the argument that a gun provides protection is a valid one. What other device gives us the ability to point and click and stop someone literally dead in their tracks? This is the problem, and as I see it one that is asking for a technical solution. Consider a device with the following attributes: - It is extremely quick to deploy. Just as quick as drawing and firing a gun. - It can be used multiple times in succession - It renders a potential threat (say a hostile person with a gun) inert or otherwise incapacitated - It is affordable, $99 or less. - It is difficult if not impossible to block (no Faraday cage armor) Now, how might this be done? Can we induce paralysis remotely without deactivating critical muscles like the heart? I know about TASERS (TM), and from what I understand the primary drawback with those is that they are only one-time use weapons, once deployed they aren't easily reusable (I.E. if you miss you're out of luck) and their range is not equivalent to a handgun. Can one of you smart hackers find a link to a scientific paper about some sort of field that makes rats fall over? As a blind person, I would love it if the device could simply be pointed in the general direction of a threat and cover a wider area, say a shotgun stun device. This has interesting second order implications which I haven't thought about -- what happens when you can easily go up to someone, shoot them, paralyze them for 30 minutes and steal their stuff? But all things considered, if someone is going to steal my stuff, I'd rather live through the experience. Thoughts? Am I completely off base? Or is this a reasonable way to approach the protection part of the problem?
