I actually don't think microwaves are doing a thing in regards to these shootings. My only point in mentioning microwaves is to show that direct emotional effects can be created in a person using external forces. ... The amount of chemicals that would need to be released is dwarfed by the size of the country.

I think it's a matter of potency, and of thresholds. Millions of people don't commit mass murder - most notice nothing. But amongst millions of people, there's a statistical percentage of those who will experience increased stress and instability.

They can be identified, manipulated, directed, and given a gun and a target by a network of handlers.

Its just a matter of coordination, and playing the odds.

Your points are well-taken. In statistics, these people who break under that chemical or radiological strain would be outliers, outside the standard deviation, but still would exist.
