re: #66 Targetpractice

Considering the amount of money that had to be sunk into buying the tactical gear, the weapons, and the improvised explosives, I’d say the possibility that more than one person was involved is pretty high.

Indeed. He had more ammo than one person could carry, and two long guns, which can only be used one at a time. Perhaps he had planned to work with a partner, ala Columbine, only to have the second man back away from the plot.
