I worked as a teacher in the public school system in New York City for several years, and I was a victim of the layoffs, you know, in the mid-'70s. And then I worked as a sales engineer for a company in New Jersey that was selling industrial filtration equipment.

The truth is that killing innocent people is always wrong - and no argument or excuse, no matter how deeply believed, can ever make it right. No religion on earth condones the killing of innocent people; no faith tradition tolerates the random killing of our brothers and sisters on this earth.
