LOL if being prohibited isnt the standard for whether or not its excessive then how can it be a fact that it is excessive b/c its prohibited?
Are you fuking serious kid?
Seriously, retardo? It's not rocket science.
If you are a surgeon and your hospital bans the use of a certain type of medication in surgeries because it has a high risk of death for certain patient, yet you use that medication anyway, then your patient dies and the medication was a contributing factor... you were a wreckless surgeon.
Now, if you are a surgeon and one of your patients dies after you operate on them, yet you followed all of the rules of the hospital, you may still be at fault. Maybe you didn't read their chart carefully or weigh the appropriate risk factors. It's more of a gray area.
The way most people, cops or otherwise, fuck up at their job is in gray areas. When you downright violate the rules of your job and it results in death, you're not in a gray area. Whether or not the medication was banned by the hospital or by the fda doesn't make it less wreckless.
