That's what I was wondering on the EDI Thread. Had it been an actual firearm, I'd have been thinking it was potentially a forgetful Auxiliary Federal Air Marshal, or however they are styled, but I don't think a taser is covered by this
FWIW, the feed of EDI news into the channel has been a little off the boil of late, even missing the bit about the passenger who died after apparently falling from a passenger lift from plane to tarmac back in October(? IIRC). I think we may need a fresh crop of news gathering "moles"
