I am was searching the net today for any reference to "to the policemen" and "I am God", with the latter phrase combined with the word "sniper" in the search criteria.
I came up with a hit to an ezboard chat board for "Romance of the 3 Kings", which appears to be a role playing game.
Anyway, one of the participants, who goes by the screen name "Lordostrategy", joined the board in July 2002. In his postings since that time, he has had the following two 'sig' files that he has attached to his posts on the chat board. Note, these were posted BEFORE the shooting started.
1. Who am I? Who am I? I, am the incarnation of Death. I am your executioner. I am your murderor. I am your destroyer. I AM GOD.
2. "Never run from a sniper, you will only die tired...." Emperor Sima Kai of the Han Kingdom. "I am the God of Death"
Now, I am not saying this guy is the perp but it is possible that the perp is involved in this scene. I am going to spend some more time researching the game, the chat site, and Mr. Lordostrategy. Here is a link to the chat site. NOTE: Going there launches a million pop ups.
