I fail to see why this new video is so ‘disturbing.’
He was casing the joint before he carried out his evil, was outside of the fenced area so he didn’t have to go through any security checks, and he had a nearby van to keep his backpack and rifle within reach.
He may even have had a bicycle in the van that he used for getting to the building with his backpack on.
Wrong guy.
Start at the twenty two minute of this video—and watch for ten minutes:

I for one, am not disturbed by a 3 second video of people walking.
