Fifty years ago, the top disciplinary problems were running in the hallway, talking out of turn, and chewing gum. Today’s transgressions include physical and verbal violence, incivility and, in some schools, drug abuse, robbery, assault and murder.” (David Johnson, 1995) Mr. Johnson's quote is relevant now in 2014, more than it was in 1995. In that year, you wouldn't even think of something as terrifying as the Columbine High School massacre or the Virginia Tech. In 2007, the Virginia Tech massacre occurred, the perpetrator killed 32 people and many were injured, making it the deadliest shooting in the United States.
