Man kills 5, self at Northern Illinois

What the hell is going on here:

The shooting was the fourth at a U.S. school within a week.
On Feb. 8, a woman shot two fellow students to death before committing suicide at Louisiana Technical College in Baton Rouge. In Memphis, Tenn., a 17-year-old is accused of shooting and critically wounding a fellow student Monday during a high school gym class, and the 15-year-old victim of a shooting at an Oxnard, Calif., junior high school has been declared brain dead.

If we keep raising our kids in such a sheltered form, never allowing them to be yelled at, never making them suffer the consequences for their actions, these things are going to continue to become more common as kids are unable to deal with stress and disappointment
