ACMARINA, thanks for the info on how the SAR Teams are organized and work in your area. I know that various states and local areas have different methods of SAR efforts, and different makeups of the Teams.
As for the reasons that the LASD utilizes Sworn Reserve Deputies, there are several. First, in Southern Calif., many SAR incidents will have either criminal or the possibility of criminal causes. Not all, of course, but enough that the potential crime scene must be protected, and the Reserve Deputies have the training how to do it, plus, have the authority to keep anyone else either not sworn, or a LASD Civilian Volunteer SAR Team Member, away.
Let me add that an LASD SAR Team, will ALWAYS have a Regular Deputy or two, who is/are in charge (Coordinator) of the Team. In addition, Regular Deputies have "regular" duties, whether on the street, administratively, or in detective/warrants duties, etc., etc. Because of this fact, plus the fact that a Reserve Deputy SAR Team is on duty 24/7/365, a Reserve Deptuy can be called out at any time of the day/night, for SAR work anyplace in L.A. County (7000 square miles), whereas a Regular Deputy has regular working hours, with days off per week. There is no "overtime" for Reserve Deputies.
Reserves also have the time to go through constant training on SAR skills that would not be necessary for a Regular Deputy, and would take time away from his/her duties out on the street.
Sometimes, one County Sherrif's SAR Team will help out another County Sherrif's Team, depending on circumstances.
Many SAR incidents are regarding "lost person/child," or "bad hiking/climbing accident up in the remote mountains," etc., etc. But IF there is any possibilty that a SAR incident might involve criminal activity, i.e., Homicide, then Sheriff's Homicide detectives and Forensics are either choppered in by LASD helicopter, or driven in on LASD 4x4 vehicles. The SAR Team will have contained the scene beforehand. ANY death calls in the same Teams.
Another reason for most of the SAR Team being "sworn" is because in many of the remote areas, there are meth labs, marijuana patches, and sometimes other illegal activities being conducted. Therefore, all Deputies, Reserve or Regular, carry firearms and are qualified on the LASD Range Qual courses, just as those who work the streets. Out in the boonies, one never knows what one will run into. If necessary, a Reserve Deputy has the POST authority to make an arrest. The issue weapon for LASD is the Beretta 92FS.
It's been seven years since I was there, but I imagine very little regarding LASD SAR has changed. Anyway, that's how it works there. Other areas are different, I know. No matter, sworn or not, SAR Teams everywhere do good work.
