If they are part of a federal task force then they can be from different states, counties, and other municipalities, but they have to identify that they are with the task force. Just read the end of any local sting article off a simple Google search. (You can literally order official looking vests and velcro on Amazon and even get them custom made sometimes...people are desperate and need money...morals are out the door for many people right now...be careful...lots of people are desperate and struggling to get by...)
Examples being South West Iowa Narcotics Enforcement (SWINE...yes they are aware...) who conduct most stings in CB. They are federalized as federalized task forces can have their sting numbers added to another states federal task force sting numbers to boost their total sting press release numbers into the double digits for maximum media coverage.
Notice the task force name has nothing to do with the hobby.
Omaha's federalized task force would be the Child Exploitation Task Force, they also include officers from Lancaster County/Lincoln occasionally I believe (because Lincoln has plenty of stings itself).
Again, notice the name of the task force.
The old guard guys like Burk must be lurking and laughing when they read stuff like this.
Anyway, this could easily turn into the kind of rabbit hole that could get shut down.
