Re: Good for the old man
I have successfully performed CPR & AV on a woman for long enough for her to be conscious enough to be complaining about being cold when the doors were slammed shut on the Ambulance taking her to hospital after she'd mixed alcohol with whatever the heart medication is that causes a heart attack when you do that.
Even back in those days then we were told in training that it it might be worth considering legal insurance if we intended to help random members of the public in case they sued us. I have never found this an issue; if the person is unconscious then as long as you don't give your information to the ambulance crew then nobody has your name so it's practically impossible to sue you.
However, this was long before the era of ubiquitous mobile phone camera coverage, image recognition and online hate mobs of vigilantes. These days i'm given to understand that male First Aiders have been persecuted after removing a woman's bra and saving her life via CPR. Courts will of course throw out any case brought due to the "good samaritan" protections in the law, but that won't stop online hate mobs whispering campaigns messing up your life, or you paying out for legal representation to get that outcome.
All a First Aider gets for saving a life is a warm fuzzy feeling followed by some nightmares about what'd have happened if you twitched the wrong way at the wrong time. You don't tend to get any thanks, and faced with an unquantifiable risk of financial penalties and/or being persecuted by a hate mob that might destroy your life, as well as the risk of picking up transmittable diseases from doing mouth to mouth.
That really makes you wonder very, very hard if it's actually worthwhile stopping and helping just because morally it's the right thing to do.
Now could I actually just walk away in an emergency? I don't know. I haven't ever done so before and i'll only find out if i'm forced to make a choice. But face with that sort of risk/reward one has to wonder if it's actually worth getting involved. No good deed is left without consequences these days and that does have an impact.
