I will not criticize this guy. In a situation like this there is either no decision or a "no" decision.
What I mean is that the time I saved a man from a burning car, I was up and running to it before I realized what was even happening and "oh-shit-what-am-I-doing" popped into my head only while dragging him across the ground. But then 2 other times (one just a couple weeks ago), when I witnessed motorcyclists sliding and rolling across the pavement, I hung back and dialed 911.
You never know how you will react until you do.
