Jammer Treatment
From Wiki Frakr
The Jammer Treatment is what we perform on collaborationist traitor scum. We prefer a launch tube but an airlock will do in a pinch. It is named after Jammer, perhaps the most luckless of all well-meaning individuals. The road to hell is paved with good intentions, Jammer. Why don't you think about that in the last few seconds of your miserable life as you're peeing blood and your lungs are collapsing on themselves?
And is there anything more ironic than Cylons killing Cylon collaborators? That's certainly going to come back and haunt a few of the Fantastic Four. Hopefully it drives them mad. Of course, an insane Saul Tigh will probably be hard to distinguish from the regular Tigh.
If Baltar had been found guilty, would this have been his fate, with bloodthirsty Laura Roslin ready to throw the switch? Sadly, we'll never know.
We did get to see Cally take the launch tube ride, though. That's something.
