I have no problem with using whatever you have handy in an emergency.
What I have the problem with is people who use duct tape TO REPLACE medical care. Like sticking it on your axe-gashed shin, then going home and leaving the tape on until you notice red streaks running up your thigh.
And don't say people aren't that dumb. Lots of people are that dumb. And some are even dumber.
Use duct tape for its intended purposes: sticking ductwork together, wrapping packages, and adhering very active small children to walls when babysitting.

My parents just came back of a coach trip to Switzerland. Very nice. My Father was having a quiet swear about the fact that there is always one loud mouthed attention getter - either sex - with a penetrating voice on every trip they have been on. I think that he's starting to consider the possibilities that open up when you have 20' of 550 cord, a few cable tidies and 30' of duct tape handy..........
