I Know This Must Be Crazy...

I know this must be crazy...
However, I couldn't help to take a notice that the blood during beheading from neck does notbleed profusely...

As I have noticed from movies, and my biological knowledge, the blood from cut body should gush out, however with my observance from beheading of an American and talk with a friend on beheading of Kim by terrorists, there wasn't any blood gushing out.

It is a mysterious thing... I know this is not a place to think such, however, I am somewhat a scientist myself... I could not help to notice...
