Earlier today, the ADPSR national board of directors sent a 15-page letter to AIA detailing our proposal to prohibit the design of execution chambers and spaces for prolonged solitary confinement. Since AIA's working group responding to the human rights proposal ADPSR is advancing won't meet with us, we had to write down our entire argument and respond to potential counter-arguments in advance.
You can see the entire letter here -- hope you find it convincing!
