I don't know if there was any commentary accompanying the video because I was too lazy to get up and put on my head set. I don't have speakers.
That was a pretty tight space and he had just checked it thoroughly. I'd like to say that if it was my job, I would have investigated further but, I think I would have run away just like the guard did. lol
Although, I probably would have gone and gotten someone to go back with me and check it out again. Just saying....
