I agree somewhat that such posts have to be viewed in light of current conditions around the world, including terrorism or home-grown "insurrection" (or whatever you want to call it).
With the current situation(s), it is not a good idea to post such questions. In other times, as well described problem and possible solution to a remote control issue would be fine. I think that when a question is very general, no details, and asking for something that could be use for illegal purposes, should be flagged and reviewed. Not to say it is bad, just not appropriate.
Some will argue that terrorists have other sources of information for this, and they do. Terrorists have already figured out how to use cell phones for such purposes.
It is just that no one knows if the person posting such questions has a legitimate issue or not. Are they a hobbyist or someone who wants to take on their government on their own? How do moderators handle this, as they will be damned if they act and damned if they don't
