@alex That doesn't make you brave, it makes you stupid. Those weren't isolated incidents, they were parts of a pattern that spans the entire species of pavement apes.
They are genetically programmed to be stupid, impulsive, and violent, and nothing will ever change that. Dumping money into social programs and making excuses don't help. If you're half as smart as you think you are, you'll realize that they do not and will not ever fit into or contribute to our society and must be removed.
