My bold.
Nah, these people don't fear death at all. They are so messed up with their sky pixie that they really believe that there is a better place for them and the infidels must all die, so being killed in the process is all part of the plan. They become martyrs to the cause and then their names are used by the next ones in line.
Far better to lock them up, quietly and out of the way. Where we fail is that we continue to give them a voice, albeit through their legal team, and allow them to mix with others of a similar bent.
Supermax? Solitary? Deffo. I'd have no problem with that. The life of Richard Reid is nothing to be proud of. Let him suffer appropriately, and you never hear of him now, do you? That is how to deal with terrorists, remove their voice. No martyrdom in solitary is there?
