Why? He has been victimized: http://news.ycombinator.com/item?id=95161
Although he states that race has not permeated his thought process, a casual glance over the books he wants to buy share a decided slant towards race issues:

Bear in mind that I am black, and I am empathetic to him. Put yourself in his shoes, a young guy with a new gig just trying to make it in the Big Apple, and you aren't getting paid much so you have to settle in a seedier part of the city. People attack you and rob you just because of your color. You are trying to do something generative with your life.

The folks that committed those crimes are long dead. But that is part of the ugliness of racism/tribalism: It's propagated like a tumor to non actors and good people. I've been called an epithet or ten in my day, but I've never been under physical attack like him. I would hope that I would have came to his aid in some way if I saw it happening. I would also hope that I would come away from it without negative racial views of the perpetrators, but am I that noble? I'm not so sure. I was good friends with a Jewish guy in college who got chased after school every day calling him "white boy". He overcame that and saved my ass on many an occassion, but I digress... The human mind evolved friend or foe circuitry tuned to statistics, so the conclusion his mind has come to is somewhat rational.
So what does a man do? If you're of low intelligence and have a proclivity for violence, you become a skinhead. If you're Byrne, you have an above average intelligence, as he seems to, you get your ass out of dodge and read a few books to better inform yourself as to why what happened to you happened.
Again, as a black person I can't agree with his conclusions, but I empathize with him and he would have been within his rights as a human being to fire a pistol at his attackers.
If I mischaracterized him my apologies in advance.
