This time officials are blaming unexpected demand in Asia for increases in aluminum prices spurring theft. While it is true that the spread of AFDB awareness in China -- with over a billion potential paranoids -- will eventually increase aluminum demand, we haven't yet reached the paranoia penetration necessary to explain the wide-spread aluminum theft panic that is being fomented via the AP.
More likely, these reports of metal thieves are manufactured to dissuade paranoids from wearing their beanies in public, where they would be easy pickings for mind-controllers, or to provide plausible deniability for an increased campaign of AFDB snatchery by agents of mind control. Mind-control skeptics could be encouraged to dismiss what should otherwise be the obvious, orthonoia-shattering conclusion of a rash of missing beanies by peppering the media with reports of aluminum guard-rail and bleacher thefts.
In any case, make sure your AFBD is properly camouflaged to avoid detection by thieves after either metal or your mind. If you are detected, extra securing tape looped under facial traction points such as the chin or nose will help keep the beanie affixed to your cranium.
