At least domestically, airports have been incredibly inconsistent/lenient about the "3-1-1" (liquid/gels) rule for quite some time. Today I flew from JFK - SFO, and I didn't bother to unpack my carry-on toiletry kit, which had a number of liquids and gels (albeit all under 3.4oz). On the outside of my backpack, however, I had my 12oz bottle of contact lens solution, which they seemingly no longer bother to check. A year ago they would ask me to take it out so they could check it (some kind of vapor on paper test) but they haven't done so the last few times I've been through security. On a similar note, people concerned with explosives on airplanes should consider the fact that the majority of cargo (non-passenger underbelly packages, which are on nearly every flight nowadays) are never screened, in any way. Wouldn't be hard to get a detonator (cell phone?) through security or to detonate remotely.
