The term school shooting most commonly describes acts committed by either a student or intruders from outside the school campus.
In the United States, one-on-one public-school violence, such as beatings and stabbings or gang related violence, is more common in some densely-populated areas. Inner-city or urban schools were much more likely than other schools to report serious violent crimes, with 17 percent of city principals reporting at least one serious crime compared to 11 percent of urban schools, 10 percent of rural schools, and five percent of suburban schools in the 1997 school year.  However school shootings in other countries may take on more national or religious overtones, such as the Mercaz HaRav massacre .
Some areas in the US are experimenting with the idea of armed classrooms to deter (or truncate) future attacks, presumably by changing helpless victims into armed defenders. Students at the University of Utah have been allowed to carry concealed pistols (so long as they possess the appropriate state license) since a State Supreme Court decision in 2006.
