If it helps, there are benefits to freezing during extreme circumstances, including enabling you to focus and possibly protecting against the development of PTSD related symptoms. 
We often think of freezing as an inadequate response, but part of that is because we tend to consider it in situations like this (where it almost certainly wouldn't have been a helpful response), as opposed to situations wherein remaining calm enabled someone to navigate a potentially dangerous situation, and where it may not have been obvious that a "freeze" response was part of what enabled someone to remain calm.

We all like to believe we'd do the same thing, but if you aren't expecting a situation and only have fleeting seconds to realize and act then 90% of us would choke.  Hopefully this guy is treated like a hero around town for the rest of his life. >

I think I would freeze. And I hate that
