The problem is; a lot of media networks/sites are responsible for a lot of current CTs. To be as biased as they are they have to leave out details, leave out facts, even twist facts...and sometimes outright lie. Any intelligent mind who looks into "news" even slightly indepth picks up on this, and even if in general the news segment is the truth, their biased way of reporting it (so they can hide stuff/info, blame others, follow an agenda etc.) throws up loads of red flags and puts peope into CT mode. They bring it on themselves.

^Then of course there are the real outright conspiracies.
