I don't know. If you are in posession of enough of a controlled substance to kill 300 people I'm kind of okay with a drastic response. For every Preston Thorpe who turns their life around there 100s of others who will just go out and keep endangering lives like this. I think this is a nuanced topic and 10-30 years is too much for drug possession is entirely lacking the necessary nuance to evaluate. Comparison to other crimes is not particularly useful either without going into the relative harms of each as compared to the harms of the other.
3,000 not 300 if my maths are correct (and lethal dose)
A pack of cigarettes is enough nicotine to kill a grown man. Provided you smoke them all at once.
It's a bad measurement.
How many deadly chemicals are in an average home? Every time I fill up my car with gas, I buy enough to commit dozens of cases of arson.
Intent matters and there's no reason to believe he intended to harm anyone. I believe it's a crime and should be a felony but this sentence is a bit extreme in terms of punishment fitting the crime.
I wonder what the sentencing guidelines are for possession of a firearm with enough ammunition to kill 300 people.
"enough of a controlled substance to kill" is an absurd, inflammatory metric. They guy was selling a good to willing and aware buyers and we have no reason to believe he was trying to kill anyone.
He shouldn't be in prison, period.
