That’s an interesting example. Here in my city there was a case of a transport officer crashing his car into someone. He smelled of alcohol and was slurring and it was in the news cycle with great outrage and irony.

A few days later news broke that he had died of diabetes-related complications. Apparently the smell was not alcohol, it was ketones from him being hyperglycemic.

Going back to your “standards” statement, for an individual it would make sense not to get into a car this person drives. At the same time it makes sense for the court not to convict him until he is proven guilty. Both standards have their place and rightfully so.
