Looking at the Virginia Tech massacre from a tactical perspective
On April 16th, 2007, Seung-Hui Cho shot and killed two students in a dormitory room at Virginia Tech University. Two hours and 20 minutes later, Cho entered the Norris Hall engineering building. He then systematically assaulted five rooms on the second floor. In his wake, he left 30 students and professors murdered, and an additional 24 victims injured. Within minutes, officers from Virginia Tech P.D. and Blacksburg P.D. entered Norris Hall and forced Cho to take his own life.
