I once worked for a federal investigative agency with limited jurisdiction/responsibilities, but it also  had powers of enforcement.  There was, however, strong sentiment within the agency leadership for many years against using any of the enforcement powers other than purely investigative ones such as those involving search and seizure (which rarely involved physical force BTW. The power to arrest was available but that usually necessitated the need to carry a firearm, so the leadership stayed away from both.  This approach worked fine given the environment of the day and the availability of other law enforcement organizations that were willing to exercise the "muscle" when more forceful actions were required.  In truth, the lack of "muscle" never cost us a conviction.  As a youngster, I failed to appreciate the wisdom of agency policy, but as I matured it became evident.  In later years when the older, wiser leaders had departed and everyone strapped on guns and began making arrests, I came to loath the job with its different approach toward fact finding.
