Look here: http://www.washingtonpost.com/wp-srv/metro/daily/oct02/snipershootings.htm
then look at shootings in groups of 3
123,456,789,10 11 12
They all start in the middle, move out, then go opposite side. like a triangle if you connect three dots.

Uh, whenever you have 3 points, and then connect them, you will have a triangle. Take any 12 points at random, divide them into groups of 3, and you will ALWAYS have 4 triangles. Or are you saying something else?
