If you start to look at the really big picture here, the obvious question arises: How does an unemployed medical student afford all the complex weapons gear, bomb-making gear, "flammable" booby trap devices, ammunition, multiple magazines, bullet-proof vest, groin protection, ballistic helmet, SWAT uniform and all the rest of it?

A decent AR-15 rifle costs $1,000 or more all by itself. The shotgun and handgun might run another $800 total. Spare mags, sights, slings, and so on will run you at least another $1,000 across three firearms. The bullet-proof vest is easily another $800, and the cost of the bomb-making gear is anybody's guess. With all the specialty body gear, ammunition, booby-trap devices and more, I'm guessing this is at least $20,000 in weapons and tactical gear, much of which is very difficult for civilians to get in the first place.

The mere manufacture of an explosive booby-trap device is, all by itself, a felony crime by the way. And remember: "Aurora Police Chief Dan Oates said Holmes' apartment is booby-trapped with a 'sophisticated' maze of flammable devices. It could take hours or days for authorities to disarm it," reported Yahoo News
