There is actually a non-trailer video on the channel and it happens to be "Muslim Somalian Refugee attack 60 Minutes Journalist Reporters in Sweden". Seems to confirm OP's hunch. Hard to come up with a scenario in which the same script would put that one and all the others up. Didn't review all of them but the news clips in trailer videos seem pretty different. Doubt this would be the script erroring out and uploading just the first part.
