People ... you need to start watching things like this objectively.
The clip in question had a graphic insert into the video stream.
The core question in this whole "investigation" was: Who put it there? Did everyone not pick up on that? The Sheriff even made pretty much that exact statement.
There are 2 answers to that question:
Answer 1 - The content creator
Answer 2 - Someone who hacked the account, downloaded the video, edited it and reuploaded it. This is not hard to do at all once the account has been hacked. In fact, the type of edit is something that can be done in seconds. It's a doddle!
The reason they were there was to determine which answer was the real one. If it had turned out to be Answer 2 then the exercise would have escalated significantly.
For the record, I did not get the joke - and here's why: He was discussing transformer taps for the international markets. These are places where the equipment gets sent. The people watching the video aren't going anywhere - so to suggest they shouldn't travel is completely unrelated to the discussion of where the equipment may end up.
I'm not against content creators throwing in their own personalities into their work - but they should be careful to not throw in this sort of silliness.
I also see this guy as being somewhat arrogant by not being able to see this. IF Answer 2 were to have been the case and the FBI didn't chase it up and something happened down the road which they could have picked up on by following through here, then, aside from the harm to life and limb, the FBI will get hung out to dry.
If anyone thinks I'm being apologetic here, I DARE them to consider taking on the responsibility any of the anti-terrorist forces around the world.
