I think anyone who doesn't make a good faith effort is a miserable human being deserving of whatever comes their way. We're talking about saving human life here. Therefore, if someone thanks they've done all they can, if they assume after 20 mins the person is probably gone, and they want to stop, I don't see why they shouldn't. My point is that the original post implied it was better to never start because then you're stuck. I'm trying to clarify that so people aren't so scared of jail they just don't bother helping. I see that as counter-productive to a society.
Imagine your loved one collapses. Someone who read the post does nothing for fear of being held liable because they started. Your loved one dies. In a parallel universe, that same person does it for three minutes and just as they are about to give up, your loved one is resuscitated.
Which do you prefer now? That people do nothing or that people try for 3 minutes?
Your advice is useless to me. I've already stated I've done an hour of CPR on at least one corpse. I think I've established I go beyond what most consider good faith. And in good faith, I'm trying to encourage people to make an effort, not stand back because there's a minuscule chance they'll end up in court.
I don't know what the intention was with the original post I replied to, but I can't believe dissuading people, and if you retread things with a unbiased view I think you'll see that's exactly what the original posts did, is in good faith, is helpful, or is beneficial in any way. I'm telling you, flat out, as someone who has done A LOT of first aid AND has been in court a lot AND carried a badge for several years, that giving up when doing CPR has a very, very, very slim chance of getting you charged. Like I said, the system isn't designed to discourage people from helping, it's designed to encourage and protect them. It may not always work that way, but it mostly does.
And I'm aware you didn't say infinity. I used poetic license to make a point.
