research huh
Ok,shotgun was there...But where was tech 9?...I dont think they had assault rifle either.Tech nine is clearly seen on recordings of cafeteria,and is extremely easy to draw-its recognizable like no other gun!
Also i'm pretty sure one of em had a basebal cap.You did not mention how they created a doom level that recreated the columbine school so they could practise their "mission".Nor mental condition of one of em.
