I’m not sire what you’re replying to. My comment was that using smart phones wouldn’t be effective in the way you mentioned. Relying on people 100,000 people that belong to Hezbollah to unlock their phones all at the same time to verify that’s who is holding the device. There is no possible way to make an attack like this targeted. It would always result in a large percentage of innocent casualties no matter what you do. The only use for it is a terrorist attack, which is what this was.
