[1] While he makes his share of rookie mistakes, including being responsible for having a squad car stolen, he also has a keen eye for details exemplified when he is not fooled by a "homeowner" who says he accidentally tripped his home security alarm (the man, who was actually a burglar, had a tattoo of a cross on his arm, but Amonte noticed a mezuzah on the doorpost).

[3] 10-8: Officers on Duty was created by Louis St. Clair and Jorge Zamacona, who also served as writers.

Several of the series' musical pieces were written and recorded by guitarist Arlen Roth.
