Were the cereal numbers sugar coated?
Nothing in a rifle caliber, even- the "rifle" was a pistol caliber carbine...
and why the 45 ammo? did they not find the weapon those were for?
(like the senior prank where 2 sheep were let loose in the school, with spray painted "2" and "3" on them... they searched for hours looking for a "1" that didn't exist)
