weaponizing SCPs? wow, that scary. With our current technology, 1 or 2 SCP is enough to destroy our modern society, just take a foto of Shy Guy, post it on the image sharing site, send it to everybody smartphone, and boom, million upon million will be dead.
For more subtle attack, use the Rusty Cow Bell thing, put it on a drone, let it fly around big city and watch million of people tortured by paranoia, anxiety, depression and insomnia.
