Sean Van Leeuwen has this post in the blog of the Association for Los Angeles Deputy Sheriffs (ALADS):

ALADS has long supported issuing BWC [Body Worn Cameras] to all patrol and jail deputies. We believe this equipment will serve to protect them from frivolous complaints and help prosecute criminals who gas or attack deputies while they work in the jail or on patrol.

Despite their usefulness, BWC have limitations.  Recordings are two-dimensional, potentially hindered by frame count, limited to a single perspective and other technical limitations.  They are a useful addendum to the observations and recollections of deputies and other witnesses and are not by themselves a complete documentation of an incident. The Sheriff's Department completed a two-year body camera pilot program last year and is still reviewing the data collected.  While the test was promising, it was only limited to a few deputies at a few stations. Before such a program is implemented department wide, there will have to be a commitment for proper training and funding in order to ensure the success of a future BWC program.
