I dread to think what would happen if a sudden and consistent spike in energy usage were probable cause where I live. I went two years without a television, with my main drains on electricity being my laptop, speakers, and my fridge. Once I picked up an older 50" plasma monitor and started playing my PS3 I noticed a considerable increase in cost/use. Should I have my door kicked in because I might be growing weed, even though the reality is much more innocuous (smoking weed and playing video games)?
Saying "you need to hear our instructions in case of a crash" isn't really confidence inspiring at takeoff and landing.
Honestly though, illiteracy is a big problem here. If you want proof, ride your bike down the bike path on the beaches in LA. Even with a sidewalk people will still congregate and walk on the bike path.
