So i stumbled across this post while and i thought more people knew the answer to this question, so the answer is in the game in a mission, a side mission to be exact, one of the characters explains how before everything happened lots of people noticed heavy aircraft activity leaving chemtrails in hope county and that the government is well aware of everything but they are trying to cover up the incident so it is all due to chemtrails making people go crazy i know it sounds a little far fetched but its in the game. Ill inform later as to what mission it is
