> anti-jamming technology Like what? SNR-boosting encoding tricks to get around high-power noise are not going to be fast like you want with a gun. The form factor needs to be omnidirectional. You don't have high power available in a portable device. You can't just change frequencies, because an attacker is likely broadcasting high-bandwidth noise. And you don't know whether the user needs it to fail safe (the bad guys got the gun) or fail hot (the good guys need to use the gun). After that, physics doesn't leave a lot of other options for technology to fix anything!
