The chief's schedule and location should not be widely distributed. But let's back up a moment: we're talking about the location of a vehicle, not a person. The town can rent the chief a Hertz car and a (better) toupee until the threat has been resolved. Let's look at the terms "schedule and location" for a bit. For perspective, the twitter bot in question is telling us where Musk's airplane probably is and approximately when it will arrive at a given airport. Once the plane lands, its location data is more certain. However, if Mr. Musk chooses to leave the airport by ground transport, then the bot hasn't got anything to report. Again, it isn't tracking him personally, just this one aircraft. The "schedule and location" data can only be precise for a few minutes per trip. So I'd admit that it's enough data to know which city to nuke, but I have doubts about its usefulness with any finer granularity. I posit that he wants to use the same airplane over and over because there's something in the plane that isn't in any of the other extremely well-appointed jets that he could anonymously rent. My first two guesses are a StarLink terminal and his preferred substance stash. He's choosing convenience over security and whining about not having it all.
I'm not so sure. Even if he wasn't a minor. I don't believe you could submit an FOIA to the city's school or to another government entity and get them to divulge his address. If he owned real property, titled in his own name (not an anonymous corporate entity), in my state, that property's location would be public information. But would not be an assurance that he actually lived there. People could own multiple properties, yet still rent their abode somewhere else. If he is registered to vote, then his legal voting residence would be almost public information, excepting only the last digit of the address. But he is too young to be a registered voter. Private and commercial data aggregators have tons of stuff on every human they can identify, but that doesn't mean the information they sell is legally "public".
Sometimes newer is not better. Have you considered that a 3 minute call to your broker once each year should be a less painful way to do that ?? IF.....there isn't any alternative way.......maybe you need a new investment company.
Actually my process is I type the letter up with all relevant info and send it to them saying I will confirm. Then I call my advisor and read each item and wait till he completes that transaction and then we go on to my next contribution etc for a dozen items. Hardly a 3 minute call, more like 15 and, at the advisor's pay rate, I shudder. A week later instead of them sending the contribution directly to the charity (whose address they have in writing) they send the checks to me made out to the charity and I pay the postage to send them on.
