One of the major ways that George Bush gets his way is by throwing tantrums -- as in "If you won't give telecoms immunity, I won't sign the FISA bill." And then he tries to shift the blame for no FISA bill onto the people who would not knuckle to his tantrum. Waaaaah, George! Waaaaah!!!
Face it. Telecoms have always known that they should not tap lines without a warrant. I used to work for one. They would not even tap your own line at your request to get rid of threatening and nuisance callers without a judge's ok in the days before Caller ID. They knew that spying was illegal. What? Did George tell them he would get a retroactive FISA warrant and then fail to do so? If that is the case, the telecoms have a valid defense. If it was not the case, they did wrong and they know it. Moreover, if that is the case, they really should be refusing to cooperate with a government that lies.
The current FISA legislation was offered without Mr. Tantrum getting his demands met. Good. He can sign it or not -- his choice. But his choice is no one's "fault" but his.
