Could be. I checked IMDb, and the cast listing for the 1975 show lists the character played by Rod Perry as Sergeant David 'Deacon' Kay. OTOH, the 2003 movie, lists LL Cool J's character as Deacon "Deke" Kay. Interesting that Deacon's character went froma Sgt in 1975 to regular officer in 2003 and back to Sgt. now. Then again, Hondo was a Lt. in 1975, and a Sgt. thereafter. Of course, 1975 SWAT was a fictional department (LCPD), while the others were portraying actual LAPD, so maybe that more accurately reflects the makeup of real life LAPD SWAT teams.
