Sounds like you think it depends on the news story............
No.
I think it depends on their motivation - at that time.
Right after 911, the BBC came out with a report that several of the 911 terrorists were alive and well, and reported their info stolen. Suddenly the FBI changed their position from "We know these 19 pricks did it" to "we may never know their true identities.
Was the BBC credible on that article? yes.
Now, ON 9/11, when their reporter reported WTC7 falling about an hour before it did - as it stood in the background - they were certainly not credible. She said it had collapsed. It was standing right behind her. She was reading a script with some off timing that day.
Were they credible in that piece? Certainly not.
Was alex jones credible on declaring the financial crisis was coming? yes.
Was AJ credible in everyone getting mobbed up to camps 5 years ago? No.
Do, for YOU to declare any group 0% credible is silly, bro. that's the point I'm making. You shit on AJ because he gets some wrong.
