Why irresponsible? First they were off duty. Second as a working Paramedic I can honestly say I have never seen a knife used on scene for rescue purposes. We have tools that work better and are safer to our patients than a knife. So I don't see why not carrying a knife off duty is irresponsible.
I suppose we expect our FFighters and EMT to perform off-duty as if they were on duty...just like cops. As a non-EMT or FF, I'm not called on to rescue anyone very often, so I don't have the tools for it...except maybe my SOG Twitch II...which might help in a pinch.
So, Hunter, am I right about that off-duty on-duty thing? If so, what tools do you carry off-duty?
