I have to wonder if removing prayer from schools actually coincides with school shootings though. Granted there have been shootings where a couple people get injured or killed since 1840, and the first shooting that had 14 people injured 0 dead but was also racially motivated was in 1891. Prayer was removed in schools in 1962 and in 1966 where a 25 year old engineering student shot and killed 15 people and injured 31. However I am sure people will actually blame the tumor on his amygdala that was the supposed cause of his violent impulses.
