Consider the context. An usually large amount of potentially dangerous chemicals in a residential area is an emergency situation. They responded accordingly - eliminated potential danger first, analyzed it second.
And before you downmod me again, imagine yourself living next door to this "chemist" or sharing a graywater supply with him. Then ask yourself if you still think authorities were wrong in their "overreaction".
What seems like "too many" to someone who isn't involved with hobbyist chemistry (or whatever he's involved with) is completely unimportant. You show me a law on the books that limits your hobbies and if you find a law that fits that and is reasonable, I'd agree with you.
If I was an EE hobbyist and built a small tesla coil (which many people do), I wouldn't want people living next door giving me the looks and trying to shut me down because it doesn't look kosher to /them/.
They didn't respond to any chemical-related threats, or a chemical fire, nor did he have a criminal record, so I'd disagree completely with you that there's any concern for worry.
I love it how people take it upon themselves to decide what is acceptable and what isn't.
A couple of posts earlier you said this is _not_ an example of "war on the unexpected", now you argue that because people in charge say "wtf?" when they hear what he's doing, they should shut him down just in case - in the interests of public safety.
Which is exactly the point of the "war on the unexpected" discussion.
"Consider the context. An usually large amount of potentially dangerous chemicals in a residential area is an emergency situation."
No, it's not. A swimming pool is an unusually large amount of potentially dangerous chemical - someone could die of asphyxiation if they accidentally inhaled even a very small fraction of it! Ban DiHydrogen Monoxide! Fearmongering for everyone!
I know folks who have about that in canned food. Are they a danger?
In my imagination I'm not peering through his basement window going "Oh no, things I don't understand and which therefore they must be 'potentially dangerous'! This an emergency!"
