Then they would know much more about what exactly are they doing with people's brains. Wait for it..
What if all these cases are just the failures? The actual damaged brains are others, and the damage is much more specific, like in high energy based strong psychological conditioning, making those other - invisible, not detected yet - targets, think and pursuit goals projected to them by the adversary forces.
Any brain damage is much more impactful than you think.
If I could guess it would be grey zone tactics to affect the most amount of people and inhibit their work. If you attack everyone there is less information pertaining to motive than a single target can get you.
I think it is a broad stroke attack that should not occur.
True. I guess the endgame may be "dumbing down" the "intelligence agency".
