Wow, who are these people trying to convince? A random sampling make absolutely no sense here. To have a 95% chance of catching the offending substance, you'd have to "randomly screen" 95% of passengers.
And that's assuming that the screening technique would actually catch a determined individual, which it won't, because he's a terrorist and he's thought things through.

This is the real head scratcher. Say someone did get an explosive liquid through the initial security screening. Why would they then be drinking it later while waiting for their flight?
