The comment was, to HIDE a Friendly Force of "Anti-FBI Shooters" in the School. WHEN they start really shooting kids, pop out and KILL the FBI 'Contractors'.
To this, I would ADD, ARM them with M-1 Garands. The 30-06 bullets fired by the Garand, will GO RIGHT THROUGH body armor worn by the Contractors.
WE'd save lives, and EXPOSE the FBI SCUM all at once !!!
