"Some workers report nightmares in which the violent images they reviewed replay in gruesome loops. Others experience intrusive flashbacks while riding the bus or shopping for groceries. Over time, many describe a numbing of their emotions-a flattening of joy, sorrow, or empathy-because the only way to cope is to feel nothing at all."
and bla bla bla. "Some", "Others", "many"... Wikipedia itself couldn't generate a better example of "weasel words". Like I said, we all know some people are traumatized, but all that matters is the amount. What if some is less than 1%? Less than 5%? More than 50%? The answer matters, but you are not providing answers to this.
Also, learn to basic science. Anecdotes are not data.
No, I am not watching a documentary for a collection of anecdotes, I clearly explained why documentaries don't count as serious sources of info when trying to accurately quantify things.
EDIT: And if you really know that traumatization from images on computer screens is "well-studied", you can surely link to one to three of such studies, rather than lame documentaries telling cherry-picked sob-stories.
