I remember it was xxy or xyx or something like that which was dominant in skitzos at the time. They were bragging about how they could release people they did not consider a threat back into the general public.
You are probably thinking about the Xyy men.
The link below is a fascinating article published earlier this month:

There have been rumors for decades that the CIA, KGB, MI6 and similiar agencies recruited Xyy guys to be their “licensed” to kill guys.
Exactly! It was a huge LIBERAL effort to de-institutionalize all mental patients and to "mainstream" them. It is likely the prozac zombies who do so much of this horrible violence, as in Colorado-Columbine.
It makes the liberals feel really good about closing all those state hospitals where all these poor mental patients had been "warehoused".
A mass-murder here or there is just a bump in the road to them, and is the fault of, you guessed it - guns.
