I've thought about deleting these channels/frequencies from my radios/scanners for a long time now. Glad I didn't. In a day and age of APX radios and encryption, it seems the Essex County Prosecutor's Detectives still utilize their UHF for some operations. I remember back in the day, one of the channels was used for the ATTF Task Force which was a blast to listen to. I just heard them call in for "Sheriff's Central" to advise them of where they were at. Then they called in a transport from that scene to their office. Aside from being a good find, my point it conventional is still very much alive, although IDK after this post. Hopefully this stays among us scanning enthusiasts.
