Every mass shooting event in the United States recent years has been followed by debate about whether citizens with guns have or have not been successful in preventing or stopping such attacks. One example of the supposed effectiveness of armed civilians in halting such attacks has been bruited online ever since the December 2012 shooting at Sandy Hook Elementary School and involves a 1997 shooting at Pearl High School in Mississippi.
Example:
A 1997 high school shooting in Pearl, Miss., was halted by the school's vice principal after he retrieved the Colt .45 he kept in his truck.
