No assumption. It's readers may have a vague memory of a corresponding event from last Tuesday, but they don't recall for sure.
I can tell you for certain. I would see things in downtown Baghdad with my own eyes... then 15 minutes later see it on CNN web or TV - and it wasn't even CLOSE to what just happened. Over and over and over again.
Sometimes I wondered if they were in a completely different country reporting these 'facts'. Really p*sses me off - especially after seeing with my own eyes.
I still talk with others over there - and can tell you that the media is STILL way off base on their reports.
