I'm still very new at this but learning. The Columbia PD Signal list on the Richland County Wiki page is the list I've been using for the past few months. What is out there now matches my list, but there have to have been some changes. Is there a way to verify the codes?
I monitor RCSD, and here are some examples of what I've heard:
One of the most common signal codes I hear is signal 30. This evening I heard several officers call in: "Show me signal 30 at Richland Northeast HS." There is a big basketball game tonight. Signal 30 is listed as rape, and it's often associated with a school. It cant be rape.
Officer: "Show me signal 33 at Clemson and Two Notch" Signal 33 listed as Armed Robbery.
The other night I heard a call go out "Caller is a relative and says the person lives at xxxx and is threatening to signal 12 with a 10-58 (gun)". Signal 12 is listed as No Information available. I'm guessing the person was threatening suicide.
Also, what is the difference between a 10 code and signal code? Why are both used? Do the police prefer to keep these codes secret?
