Allow me to shed some light on the actual effects so far, to the extent that I can publicly.
We know that the 58 Sheriffs are very aware of a number of drills we've run as part of this initiative.
We know that they have been communicating closely, and often. Some letters of response are word-for-word identical.
We know that at least some of the counties counsel are similarly communicating.
Chiefs of Police are not as concerned, since they are not the primary target (although strategic applications of pressure have and will continue to be applied at the city level). They (CoP) have a safety valve - '(g)' agreements. The Sheriffs do not. One Sheriff told me that a certain segment was, quote, "panicked"; this was confirmed almost verbatim by a highly-placed source at another agency.
There are some crimson threads which we cannot discuss just yet, but which will become more obvious as the initiative goes forward.
The Sheriffs are worried that stare decisis will hold, that they will not be able to undermine CBS, and that a well-funded and capable organization will comprehensively make this issue a very difficult one for them going forward. "Fundamental right" to bear via Sykes, plus enforcement of existing law across the state - with a public and accessible means of applying legal pressure as needed to compel conformance - makes for painful resistance with quickly diminishing upside.
