Never mind the lead, those kids on the video don't have a visible ASIC displayed while walking all over that Cessna's non-walkway areas and draining the fuel out.
The owner of that Cessna needs some more "NO STEP" markings on the tailplane, along the fuselage, and up over the wing. Poor kid didn't know he shouldn't - there were no signs on it! Never mind about Civil Aviation Act reg 24 either.
