I have absolutely no idea how loggers work in a police environment, but
years ago the broadcast station I worked at had a stereo (2 channel)
logger.Seems to be it would be a simple matter to feed the transmit signal
to one channel and the receive signal to the other.

Otherwise, it would be a fairly simple matter to split the dispatcher
microphone signal. Take one side of the split and feed it to a 2 input
mixer. Split the receiver output and feed one side of the split to the other
input. Take the output and run it into the logger. In a real world
environment things would be a bit more complicated as you would probably
want to do some signal processing, such as audio AGC, before recording.

thanks, I understand what you are saying that it CAN be done that way.

My question is what IS typically done?

Thelogger in question is a mono unit.

In some applications, there is a seperate receiver used for the logging
recorder, which just records everything that goes over the air. The aviation
guys normally do this, because they use AM which allows everyone to talk
over one another without any capture effect. So you may have the control
tower stepping over someone, and you want to be able to record that, so you
use a seperate receiver from the main comm system altogether.

The local police probably do not do this, since it is fairly expensive and
the police, I am sorry to say, have tended to get the cheapest comm systems
they possibly can.
