Easy. They will point out that there is no one lethal dose for drugs like fentanyl. That what constitutes a lethal dose depends on the users size, overall health, and whether they are a regular user of the drug, a fact the prosecution established. What might kill a new user would be shrugged off by a junky like Floyd.
That's how.
How do they argue that it dod not kill him. How do they stop a dead man walking from dying?
That certainly is an entertaining approach. However, the amount of fentanyl/metamphetamine and the
autopsy discovery that George's lungs were 1.5 to 2x their normal weight, being sloppy with drug induces fluid,
concludes that he died of dry-land drowning.
No amount of CPR, EMT intervention, lack of physical restraint, or ER efforts was going to save
Mr. Floyd from his self inflicted drug overdose.
