Let's make it more interesting - a hypothetical 45 year old police officer with hypertension is killed by hypothetical BLM protester. How many people promoting the "well, everyone dies anyway" would be good with the killer being acquitted because the cop was going to die soon anyway because he had a preexisting condition? Let's see how far these excuses are willing to be dragged around.
being hit by a car though is NOT a natural cause of death. If someone dies from something that is completely unnatural that ( at least to me) is different from dying from a natural cause of death while having other conditions. All the conditions he had that could have resulted in his death ( and could frankly for all we know as tough as his case was to tell) would have been considered a natural cause of death. Being hit by a car is in no way shape or form considered a natural cause of death that has NOTHING to do with what medical conditions a person may or may not have.
Well, the fact is that when it is your time to go it will happen. The most that can EVER be done is to postpone death.
