Source cod?? Oh, I hope there's nothing that fishy about it.

Cheers,
Tom

King George the W. has already tapped Reg's computer so it's old news.

"Meanwhile in Washington, Attorney General Alberto R. Gonzales
suggested for the first time on Thursday that Bush might have the
legal authority to order wiretapping without a warrant on

United States.

'I'm not going to rule it out,' Gonzales said at a House Judiciary
Committee hearing." (NY Times)

Just think, our ham conversations might be more secure than talking on
