Yeah, I wouldn’t advocate taking the ambulance and definitely not leaving your house before the body is gone and you can secure your home, but going to the ER can definitely work to your advantage as I pointed out. If someone can’t see the logic in that, then that’s just not their plan.
As far as all the other stuff you mentioned, I think it’s better to live a clean life so you don’t have a mess to clean up in a rush?
