They only way you're injuring someone with fentanyl is getting them to ingest an unsafe amount of it one way or another. That's not really different from a lot of prescription drugs. Or some OTC ones, like Tylenol. Or lye and many other cleaning agents.
The only way someone is ingesting that accidentally is if a classmate is attempting to poison them. There are a lot of other poisons that can be ingested in small doses if someone is trying to injure you. Fentanyl is not going to leap out of someone's pocket and fly down your throat. It's not magic killing dust.
If people wonder how possession worked in the middle ages, look no further than this.
i do agree with your point though.
Edit: fuck me, I was half joking and thought I'd check anyway. What a shit show. Latest case was 5 days ago. https://www.google.com/search?q=American+police+shoot+kid+wi...
Still sucks that the kid got shot for it, but I can see the confusion, compared to the usual colorful water guns.
Cops are not judge, jury, and executioners, and in fact have zero authority to hand down punishment. Being shot for holding a gun is absurd.
There’s a huge difference between simply owning a gun vs wandering around in public pointing it at people.
