I was given a primer on how they do it, by a freeper (who has since passed on).
He did exactly this, overseas, for a 3 letter agency. He would provoke candidates to act out. His formula:
1) Find a mentally-ill person.
2) Using internet (nowadays) or personal contacts (the old days) provoke them. Give them enemies. Talk of conspiracies against them. Make them (more) paranoid.
3) Make sure they have access to a device of destruction, be it a gun, a bomb, whatever.
4) Make sure they are on their meds, first, then suddenly make sure they are cut off.
5) PROFIT!
Thanks for the List,
My book club has
A Few candidates.
Wow, interesting
That sounds reasonable and not that hard to set off somebody who is on the edge anyway. Good post.
