How do you associate the death pattern of 3's?

Is it a conspiracy?

Is it just an "unfortunate" act of god?

Over the past four days there has been 3 (yes that magic number) major (news worthy) incidents of unfortunate deaths by some ill, or insane, or however you want to classify their thinking, gunman.

The first would be on March the 8th, a Sunday morning when lots of people attend church services in their local community. However, on this day in a community in Illinois, a gunman walked into a church and shot the pastor along with 5 other people. Two of the church's parishioners reacted by stabbing the gunman and wrestling him to the ground. I guess this gunman didn't get a chance to take his own life.

Then we have the 17 yr old gunman that opens fire at a school he use to attend. Leaving 16 dead, hijacking a car, driving for 25 miles before the police caught up with him. It was originally told that the police had taken the young mans life, however may have also been found that he MIGHT have taken his own life.

Last in the number of 3. The shootings in AL. A 28 yr old gunman went on a deadly shooting spree gunning down 10 people, most of which were his family members, and also killed 4 dogs. The "news" stated that he may have been "let go" from his job recently and that could have been the trigger. This is classified as the worst mass killing by a single gunman in AL history. All of this before taking his own life.

What exactly is it that "possesses" people to become killers, gunman? Can we go back to the so called "movies" like the Matrix, where chips are implanted into our brains without us knowing. Could this have some type of a conspiracy theory?
