Not having witnessed the event, I will not comment on the fault or no-fault of the driver in this case. My thoughts and prayers go out to the family, friends and co-workers of this EMT and know for certain that but for the grace of God, that I too on numerous occasions may have suffered the same fate.
What I will say, having been in Emergency Services for over 20 years, is that “fault” is a two way street. I have personally witnessed many times when 1st Responders (Police, EMS, Fire/Rescue) have developed tunnel vision or a sense of invulnerability and do not take proper caution when working in potentially hazardous areas. I have had new guys pumped on adrenaline pop out of the apparatus without even looking to see if another vehicle was coming. On the other hand, I have also witnessed (more frequently) the poor judgment of drivers, both in-route to a call and as they approach the scene of an event/accident. Many times when in-route and you are approaching a vehicle from behind, they suddenly realize you are behind them, they freeze, slam on their brakes, forcing you to take evasive action.
