If it ain't this device then it's your wife's roomba robot calculating the layout of your floor plan and beaming that back to the Stasi office.
Back in the Good ole days, the SWAT would do a typical army four-man stack, bust your door down, you'd get to take down number 1 guy, number two guy would trip over him and you'd miss that shot, and either numbers 3 or 4 would get ya bit they would be stumbling over your end tables and standing lamps on thier way in.
Nowadays with Roomba they can make a layout of your floorplan, build a mockup on a warehouse somewhere, practice a billion times before taking you out, memorize 'go left, five steps, bookcase, three steps, turn right ascend thirteen steps, turn right...'
All on the dark and by rote memorization. All that before even pulling up to your house.
You'll not get a one of em anymore nowadays...
Not fair.
It's the rommba that'll do you in when Big Brother comes for you, not your fleet tracker on your truck.
