I see liabilities and find myself saying... "Get over it, life has risks!"
Unfortunately as someone getting higher medical training than most civilians and other Law Enforcement, I also find yself looking down that barrel from the wrong end. If I save a life I am heralded as a hero, yet may still be sued for a broken figernail on the victim. (Actually, Florida as the good samaritan act which protects me but still..)
Also as a diver and hanyman and poor folk who gots ta do stuff myself cuz ah cain't afford high prices, I love doing my own repairs rather than paying twenty dollars an hour to get someone else to do the same thing I can do.
As for other regulated industries, the medical industry is famous for "leave it to trained technicians" mottos. So is Law Enforcment.
When our armorer had to be sent to Smith & Wesson's armoring class to be allowed by State Regulations to replace grips on a State weapon!? Ludicrous? HELL YES!
I wish this ere a simple issue. I agree that there are very simple user serviceable parts on our life support gear, unfortunately, I have also seen the other end of the liability issue. Wish we could return to simpler times before people sued over having HOT hot coffee.
Note* Do not use hairdryer while showering. Do not insert hot curling iron into body orifices... actual warning labels due to stupid lawsuits. Oh well, welcome to the land of opportunity.
