Feel free to do whatever Mr. Hannity suggests. I'll be following the advice of a professional firearms instructor.
The instructor is absolutely correct, but that approach does come with it's own set of unintended consequences.
In California, CC regulations vary by county, but it's pretty much universal that a licensed carrier must inform the LEO that s/he is carrying.
There has been a bit of confusion on the part of individual LEO's about when they should be informed by the individual they're interacting with, and I'm aware of more than one incident where a licensed carrier did pretty much exactly what the instructor advised only to find themselves in custody (temporarily) for not informing the officer at the onset of the encounter - in one incident, an individual was approached by an officer responding to a suspicious person call (which the contactee wasn't), approached the licensed carrier and began questioning the individual. According to the carrier, he attempted multiple times to inform the officer he was carrying only to be told to shut up, and when the contact went to a Terry search the officer discovered the carry gun, immediately took down the carrier and commenced subduing him the old fashioned way - witness accounts described the officer striking the carrier with his baton while dragging him by his hair towards the patrol unit.
End result: cash settlement, all charges dropped, medical bills paid, firearm returned - in exchange - no public civil suit filed.
The officer in question in the above incident was eventually fired from his agency, not for excessive force or other incidents involving his poor decision making but for totaling his patrol unit, driving in an area out of his departments jurisdiction. No assistance call, no pursuit call, -0- reason to be where he was doing what he was. Pretty clear to observers that he was using that particular road for what many folks used it for, performance driving on a beautifully curved stretch of pavement.
