Either you are wrong or the article's graph sourced from the US department of energy is. It shows no significant reduction, only a slight dip before a continued upward trend.
Why would you try to introduce facts into a discussion about climate change?
"You fly to Europe or Canada, and their security personnel have a clue - they're practical, they keep a sharp eye out, and they use the right response for the situation at hand."
The problem is that here in the U.S. we have to be oh so politically correct at all times. We have to treat 74 year old white-haired grandmothers *exactly* the same way as we treat 20-something guys with a bread and a strong middle-eastern accent when everyone knows that the odds of someone from either of these two groups doing something harmful on a flight are massively skewed towards the latter group.
I think the potential threat of the latter group would depend on what type of bread that 20-something middle-eastern guy has. Pita? Not too worrisome. White? Not too bad. Whole wheat? A little unnerving. French? Time for the full body scan.
The tao that can be tar(1)ed is not the entire Tao. The path that can be specified is not the Full Path.
