And I will continue to say them as often as required:
Torture is never necessary.
There is no legitimate military, criminal justice, or public safety goal that can possibly be achieved or supported by torture.
Torture undermines real security.
The best sources of information in counter-terrorism have always been informants of conscience. A policy of employing torture deters such informants from coming forward both out of fear it may be employed against them and by making security forces and the states they represent less sympathetic.
Torture diminishes us as a people.
If we are not willing to hold ourselves to the standard of conduct that the international community has set as a bare minimum for participation, what justification do we have to insist those standards be upheld elsewhere?
The ends never justify the means, the means corrupt the ends.
