I read the article. He seemed to think that the 6-7 people who witnessed him being robbed by two muggers, one of which was armed, should have "helped".
The odds are pretty good that the 6-7 onlookers were also unarmed and if they had stepped in to help they would have been putting their own lives on the line to protect another person's property. Even if one of them was armed, they would not have been justified in drawing a weapon solely to protect some other individual's property, and doing so probably would have left them at the mercy of a liberal DC prosecutor, or dead.
Typical liberal mindset. Thinks he should be protected by others without taking responsibility for his own self-defense. Hopefully, he has gotten a wake-up call and will now be more sympathetic to the position taken by individuals who actually do have the balls to take responsibility for their own protection.
