Since this happens to be a common topic because people do illegally use digital voice on GMRS, here are some things that might help if anyone wants to really get into decoding digital voice -
Nooelec SDR dongle $34
SDR console (free software)
DSD plus ($25? for the software)
Hook this into you computer, slap an antenna on your SDR (preferably an outdoor antenna) and start sweeping through the frequencies. When you come upon a digital signal, DSD plus will automatically start decoding what it is and will tell you exactly what they are running as far as time slots or if it is encrypted. The only thing it seems to have an issue with is Yaesu Fusion (something that seems to get used in areas where it isn't supposed to be used). After that, you should get a good idea who it is, especially if its a Ham. 9 times out of 10, Hams will do something dumb like this and not change their Ham Radio digital ID on the radio. DSD plus will pick it up.
Could you expand on fusion misuse? Is that from Mars mod radios or another source?
