In the real world in which we live, you always have to choose between evils. And in choosing between evils, you have to have moral criteria for how to make those choices.
To ask about the 'source' of rights or morals assumes an erreous conclusion. To ask about the source of morals is to assume that such a source exists. As if it existed outside of human constructed systems. The 'source' is the human ability to learn from experience and to entrench rights in our laws and in our consciousness. Our rights come from our long history of wrongs.
The sad reality is that there are no purely domestic issues in Israel. Issues that would be dealt with by municipalities in other countries - such as how to deal with a dangerous bridge or how to resolve conflicts between religious and secular bus riders - become major international issues when they occur in Israel.
In the Pentagon Papers case, the government asserted in the Supreme Court that the publication of the material was a threat to national security. It turned out it was not a threat to U.S. security. But even if it had been, that doesn't mean that it couldn't be published.
Our First Amendment expresses a far different calculus for regulating speech than for regulating nonexpressive conduct and that is as it should be. The right to swing your fist should end at the tip of my nose, but your right to express your ideas should not necessarily end at the lobes of my ears.
When I was growing up, my mother would always say, 'It will go on your permanent record.' There was no 'permanent record.' If there were a 'permanent record,' I'd never be able to be a lawyer. I was such a bum, in elementary school and high school... There is a permanent record today and it's called the Internet.
We live in an age where there is both more expression and more self-censorship than existed even a decade ago. Alas, laws have immunized internet carriers from many of the usual rules that govern public dialogue. Rights must always stay ahead of technology to assure that constitutional protections apply to all forms of communication.
