Well, the other stuff sounds fascinating (kinetic energy weapons,
Vulcan nerve pinches,) but wouldn't a close approach of a magnet
mess up the guy's tape as well?  Maybe it would have to be as big
as the Edmund Scientific half-pounder (just to make sure) but it'd
be simple.

On the other hand, you still have to worry about pacemakers (they
adjust with magnetic gadgets of some sort) and your own nearby
diskettes (!) and any metal-detection or theft-proofing (likely
including library) passageways you have to go through.

You'd also have to get close to the dude and put your magnet
near or on his deck.  Would he be able to figure it out?  How
fast can you move if he can?
Cheers.
