I am at a loss to explain why the Guard Police have never been hunted down.
Like most offending, it would die out if action was taken. All that's required is a little co-operation between a few military units and it could easily be incorporated into a training exercise to provide a training benefit to all of the units concerned, as well as the wider GA/CAT community.
If they can be heard on Guard, then they can be found. The D&D controller has to deal with the initial call, but if resources were on hand to tackle the other aircraft transmitting, and suitable words of advice given, things would be safer for everyone.
