Quote: If they had been exiled they wouldn't have been able to do that.
No, but they could have tried it on their fellow exiles. A few problems with the exile idea. How do you keep the exiles buddies from picking them up and bringing them back? Do you provide and law and order for the exiles, or are they free to prey on each other in any matter they wish?
Which brings us back to capital punishment. If we are too squeamish to execute the worst of criminals, does throwing them into the penal system and allowing their fellow criminals to do the job really absolve us of responsibility for their deaths?
Yes, Because they know that commiting a felonious act will get you dropped at the exile island. That makes it quite like placing your hand in a lions mouth. you know he will bite so if you do, the lion is not guilty you become stupid for putting your hand in there. As far as insuring that they never return here but remain on the island. Thats cheaper and easier than maintaining prisons. #1 use an island near a military base so it can be defended easily, and without added expense. Then watch it with a single satellite that we have up there already, like one of the google earth rig or one of the many miliary rigs. Its easier to pay three or four shifts of three guys than the thousands, maybe hundreds of thousands we employ now as prison guards now. And it should be markedly less expensive than maintaining huge numbers of extremely expensive buildings.
They will certainly have less of an opportunity to escape than that fella locked up for 21 years in an apartment. Then after 21 years if he don't escape he comes back into society to do what? Kill again, resort to robbery, to pay for his meals, get on the welfare ******. What can a man who is so twisted that he kills so many bring of value to the table of society. If the evidence is so over whelming that he is guilty death is the only humane punishment to him and soiciety.
