Tor exit node operator arrested in Russia (TorServers.net blog)

You may recall the San Bernardino shooting in 2015. The neighbor gave his weapons to the shooter. The law in the US saw him as having some culpability in the subsequent actions of the shooter.

Had the weapons been stolen from him, then I doubt Marquez would have been prosecuted on that charge. (Unless the weapons were readily accessible, which is a different complaint.)

While the link to this Tor operator is specious (weapons have one purpose whereas knives and Tor have other utilities; knowledge of intent) the law says there is a difference between stolen, given and sold.
