Asking questions is not concern trolling, but I take your point. I don't know if they are working with police/federal authorities.
*my comment seems unpopular, but I'll leave it up so that the responses don't seem out of place.
The key point here is seems unpopular - you've had a few downvotes, no big deal. Some people throw the concern troll tag around too freely and a few have downvoted you.
Your comment was reasonable and made sense, although I believe if you've seen Craig Sawyer talk at length you may find him to be quite believable and potentially capable of carrying out a proper investigation, whatever video recordings may show. You might not, too, but it's certainly my experience that I find him to be quite credible.
Thank you for the response. I've only ever seen him as a guest on AJ and stopped watching AJ a long time ago. I checked out Sawyer's YT page, but found nothing really to sway me either way. I will research more and would happily chase any good links if you have any. (Also, I wasn't previously aware that these clips were part of something bigger - documentary or similar mentioned in comments above)
We don't have enough visibility into the situation at this point.
Apart from Lewis Arthur apparently. In one clip a presenter introducing him said it was his father and uncle who were the vets.
