I love it! A terrorist pulls out a detonator any you quickly pull out the porkrinds. He realizes that he won't get into heaven and meekly allows himself to be disarmed.
Of course, if he doesn't see the porkrinds in time, he might still blow himself up, taking everyone around along with him. Then, when he gets to "Muslim Heaven" he finds out that he is not allowed in because he is unclean. The murder of innocent civilians, of course, is no problemo.
Seriously, your idea has promise as a deterrent. If civilized countries announced that all cars, trains, buses and planes would now have their walls lined with pork products, perhaps these lunatics would think twice (or, in their case, once) before wreaking their havoc.
Put a pig on every flight, bus or train? No Muslim would dare board much less destroy him/herself on the thing.
