People who are paid not to make mistakes are doctors, airplane pilots and ammo manufactures. Yes, it happens, but when it does, it makes lawyers salivate. With todays technology, this shouldn't happen, when lives are potentially at risk. Just sayin.....
Yes , but the doctors aren’t the ones designing and manufacturing the implantable devices , surgical tools/equipment , etc . Sure , if the doctor leaves pliers inside me after the procedure is done and I live through it , yes he/she will be hearing from my lawyer .
Sure , if a pilot is going to careen towards terra firma at 600 mph from 30,000 ft he’s going to definitely hear from my lawyer if I survive . However , the airline pilots aren’t the ones designing and manufacturing critical jet/plane components .
How about the uneducated machine operator at the bullet/powder/primer/ammunition manufacturing facility who happens to be going through a divorce and is either hung-over from the night before or on psych/nut-pills or illicit drugs ?
The tough part about handloading is most (if not all ) firearm manufacturers disclaim that using any such loads in their firearms voids any warrantees .
With factory ammunition there are identifying properties that they can use to determine conditions that aren’t present in handloaded ammunition . That is why the “ authoritive figures “ in the forensics field state to always save the containers that defensive ammunition comes in ( make , model , date code , lot code , etc ) .
The only caveat to that is most end users of the factory ammunition don’t have a lawyer on retainer ready for this kind of litigation . Most will not even attempt to correspond with the firearm/ammunition manufacturers after an catastrophic event for fear of ridicule or blame .
