Frankly, I could care less what the family thinks. If they feel so strongly, then they should advocate for some legislative change. Most families would kill if given the option, and also the luxury of having someone else do it for them.
This is literally what they are all about. It's like complaining that the IOC keeps whining about athlete doping just to try to stay relevant.
That said I have though about it more than once, simulation in the head style and a world were PETA wins turns in to a uglier world in most cases.
Note: this is specifically about PETA, some other animal rights/welfare organizations are somewhat reasonable.
Why would anyone want to add complexity to triage would be my knee jerk wonder, it’s supposed to be a quick process
Would the hospital need to wait for the legal system to get back to them before treatment can begin? How would you know if the patient has committed a crime without waiting?
For the first one, I can totally understand what the victim's family must be going through, but doctors aren't (and shouldn't) be in the business of making moral judgements on who should and shouldn't get to live. There is an established process in place for organ transplants (time on the wait list, viability of the transfer) and that's all that needs to be followed.
