I think this near tragedy opens up even bigger questions about helping people in general. If that guy knew how to use a knife, of if he was smart enough to get Jeff or someone else out of their vehicle it could have ended a lot differently. I have to admit that over the years I've questioned my attitude towards assisting people at any type of accident or disaster. Just recently, I was on the scene of a multiple fatality accident in CO and now attorneys are calling to schedule a deposition. Although the questioning does not involve my actions as an EMT-T, but rather, the weather conditions involved in the accident, I still have to retain legal counsel since I was involved. Although most states have "Good Samaritan" laws, there is no guarantee you will not require expensive legal counsel to protect yourself. Fortunately, I have access to multiple family lawyers, but it's still a pain.
In this case, rendering aid to anyone who appears to be "out of it" is risky. People can be dangerous for any number of reasons, not just criminal intent. Jeff did the right thing by staying in his car. During Hurricane Andrew, I had some guys flag me down (like there was some type of emergency) then try to hijack my vehicle and grab my photo gear through a window -- but I was ready, with my feet on the brake and accelerator so I punched it and drove off rapidly, running over at least one foot.
