I don't want to point fingers... but I have to ask, "
Jack, did you have anything to do with this?"

OTOH, I have to admit that upon returning home after running an errand, I hear my scanner cycling back on. Perhaps I have done something to affect unintentional with my headless mini!

With no one to 'monitor' it, I suppose it could be doing things to the interweb pipes!!
...or maybe it's just the NSA having a tantrum...
