No Lawyers - Only Guns and Money: Purdue University Homeland Security Institute: Guns In Schools Save Lives

Via No Lawyers - Only Guns and Money:

Dr. J. Eric Dietz, director of the Purdue University's Homeland Security Institute, presented research at the recent NRA Annual Meeting in Indianapolis regarding active shooters in schools. Their threat assessment modeling program examined the active shooter scenario and looked at factors that would be most effective in reducing casualties. These factors included locked doors, school resource officers, and staff carrying concealed.  

The control scenario was just a school with locked doors and no resource officers or staff with concealed carry permits. The researchers found that the control scenario had the most casualties and the longest response time. Their model showed that the response time would be 10-12 minutes and an average of 20 casualties. Their model used historical active shooter data to arrive at this.  

When a school resource officer is introduced to the scenario, response times dropped to a quarter of the original times and casualties were reduced by two-thirds.

It makes perfect sense, if you think about it calmly, rationally, and without any bias against firearms. If Lauren Rousseau or Rachel D'Avino had been armed, they might not have lived through Sandy Hook. They might still have been killed, along with all of the children in the room with them.  However, no one in their right mind could argue that things might have been different. Instead of helpless victims, they might have been survivors.
