This comment is manifestly made in bad faith.

I want the police to arrest, and DAs to prosecute, organized theft rings. Someone with several stolen bicycles is not a small businessman, he's a fence, and should do several years of time.

It is in fact quite easy to tell that person apart from the guy who bought a bike on Craigslist and oops, turned out it was stolen.

You're pretending this distinction is unclear to you, and insinuating that I'm proposing Soviet price controls. In reality, you are perfectly aware of the distinction and know that I'm not. That is arguing in bad faith.

How do you prove he's knowingly part of an organised theft ring? Simply not checking the provenance of the goods you buy doesn't prove that.
