But you have still to establish how there's an appreciable chance of a moving short range jammer (anything with a lot of power would drain batteries too fast) could lead to a death.
I already have established that. Many people use their phones for emergnecies (some people have phones on them
only for emergencies), so jamming peoples phones (particularly for such a silly reason like "it violates my morals") can very well inhibit their use in such a case.
How short is short? Your jammer still has to serve its function and stop people from livestreaming you, so it would have to have a fair range. A 1m jammer probably won't be particularly dangerous, but it won't stop people from livestreaming you either. A 5m one wouldn't stop people from livestreaming either (I am pretty sure the Google Glass has a good enough quality camera to distinguish people from 6m away) but would piss off some people.
You would probably need something around 30m or so until you become indistinguishable, but then you are pissing
a lot of people off (the denser the population, the higher chance of being livestreamed). Its not just people in the immediate vicinity either, as you move around you will cause peoples conversations to end abruptly.
How can you justify doing this anyway? You are going around and disrupting peoples phone usage, while asserting that your cause is more important than them. To most people, being livestreamed isn't some great violation of morality. You haven't actually justified doing any of this yet, and your response to the idea that you are negatively affecting other people seems to be "screw 'em". Your morals are above the law,
and above other people apparently. You haven't explained why being livestreamed is such an abhorrent violation of morality.
