This is eerily reminiscent of the diagnostic skills displayed by Tennesseee's answer to Dr. Mengele, Bill Frist, when he determined that Terri Schiavo was NOT in a persistent vegetative state, and was responding to visual stimuli. (The autopsy later proved that her brain had atrophied to half the normal brain size, the damage was irreversible, and that she was BLIND.)
So, based on the forensic abilities of Stella Tremblay, who appears to be the bright, aware one in her family, we have moved from the government's setting off its own bombs to the government's inventing its own traumatic-amputee cyborgs to lie on the sidewalk. I think it's time for someone to sneak into Stella's house late at night and steal all her radios.
A big h/t to Tuck @miscellany blue.
