Holding KSM’s trial there would be a tacit admission that Gitmo is perfectly suited for what GWB used it for-housing the mad dog killers of the Jihad. That’s why it will never happen.
As a sensible alternative settle for holding the trial in Detroit.
The value of the city is so low now that a major bomb going off there would not cause any real damage, in fact it would contribute to demolishing the place.
Also, since that is jihadist controlled territory anyhow, it will just damage them.
