You can cancel, but most IP's are too fast to do any good. i.e.,
I'll cancel this one.

You do it fast! <G>

With Thunderbird you can right click on the message, the bottom option
in the dialog box that opens up says "cancel message", and it really
does work.

That happen often in many states here. The parole boards won't let you out
if you don't express sorrow for your crime. Hard to do if you were innocent
in the first place. A recent multi page article in the L.A. Times just
covered one such tale
Kid was convicted of killing his mother when he was 17. 25 years laters it
turns out the investigating officer lied and also did a sloppy job of
investigating other possible suspects. It was so bad a miscarriage of
justice that the original prosecutor has been working for over a year to get
the kid a new trial. One problem is that about ten years ago he said he did
it and "expressed remorse" at a parole hearing. He said it was a stupid move
but he thought  he would never  get out.
