Hello, as I mentioned in my intro post, I'm an amateur chemist (and insomnia sufferer, if anyone is wondering about the time!) The amateur chemistry is pretty divided about what to do in terms of police, some people would send a letter to the station in advance to prevent any misunderstandings, others would avoid contact at all costs.
There are some pretty scary and ignorant stories out there, I've heard of a person being arrested for public endangerment after he ran a pump backwards to remove air from a glass jar in his apartment building. In another case they couldn't prosecute a guy for anything so they argued he was violating zoning by-laws by doing chem in residential zoning.
The problem is that to do some more interesting experiments, I need chemicals and equipment that are closely associated with illegal activity. The last thing I want is the very people protecting society breaking down my door to stop me from doing something educational (and legal). And yes, I am following local fire codes and shipping regulations (Seattle, Washington area). And disposing of chemicals properly. And I keep a lab record and would gladly give inspectors tours. I know people are worried about crime, but the same way that guns are legal despite shootings, it's unreasonable to bust down every home chemist because of drug cooks and terrorists, especially when the law doesn't proscribe any explicit bans (except the catch-all "public endangerment").
Any advice from the real police?
