OK - so we have had pics of William Boyett and Ken Lynch, how about one of the OTHER guy from the 60's/70's who was always a cop/military officer in shows - Ed Peck. Peck was best known as the local cop in Happy Days
, whose character was known as....Officer Kirk! Someone at HD was most likely a Trek fan, and thought it might make a nice inside joke... it WAS done at Paramount, after all.
One funny thing is that Peck never appeared on Dragnet or A12 at all - especially not as a cop!
