This group came up, when searching for "Constitution Keystone."
They're a progressive group that actively works to change the meaning on the Constitution, and they talk about Scalia quite a bit - about how his method of Constitutional interpretation was wrong, and generally relish the fact that he's conveniently gone now.
Included is a list of names to watch out for, and see if they occur anywhere else.

I'm thinking this might be a front for a three-letter-agency.
