I got this following excerpt from a very reputable monthly magazine which includes wonderful photography and in depth social commentary, Maxim. Every once in a while something useful and intelligent slips through.

Under my proposal, no torture would be permitted without a 'torture warrant' being issued by a judge... A torture warrant would have to be based on the absolute need to obtain immediate information in order to save lives coupled with probable cause that the suspect had such information and is unwilling to reveal it.
  -Alan Dershowitx, Harvard Law Professor

I like this proposal because it seems to allow for a last resort technique in a fashion reflecting its disadvantageous nature. With a full system of checks and balances proved through time with warrants of other types, it seems that this method is less likely to produce unnecessary torture. I don't like the warrant-less nature of current methods. Although the government states they do not "torture", their definition of torture is a little bit conservative in nature, allowing for more methods than it restricts. Security concerns should be moot, as court proceedings for these matters could simply be sealed, and their outcomes classified for many years to come.
