@jwz I'm not certain what your concern is. I saw that web site a while ago, the one that you link to, and I was struck by how much it mimics the tactics in the old 1950's/60's CIA sabotage manual that was popular to have in the 1980's. It says, "for the 21st century", which is funny, because I feel like it was written before, around 70 years ago, with only slight changes.
