Re: How terrifying
Well, most states have proven that they have and like that tech. There are also cases where someone was operating it, but the police never found out exactly who it was. Most of those I've seen were presumed to be state actors, but since we can't prove that, it's always possible that it was someone else. Since the hardware can be built by a nonstate person, it's not that surprising that some people have done this. It doesn't have to be a concerted effort for some new concerted effort to pick up the practice.
