In countries where the law does not dictate that all carriers maintain
extensive logs, this is fairly simple. Whether you are a Tor node or a
normal ISP, you do nothig until you get a court ordered warrant, at
which point you  collect information passing through your network and
hand it over to authorities.

So the "Tor" service remain anonymous until the police suspect illegal
data passing through it, at which point they snoop what passes through
and work they way up to find the true origin of the data.

In countries where log files must be created and retained by law, this
is less simple. Is a Tor node covered by the law ? If so, then it is non
compliant of it fails to colect the law mandated logs.

If the Tor node is not covered by the law, then law enforcment cannot
complain if there are no logs to analyse.
