Most of the officers I worked with would give 10 mph , some times they stop for a warning under 10 then rarely issue a citation for under 10.
But every once in a while a person stopped for 9 over would beg for a citation
Some people just open their mouths up and ask for a citation instead of a warning.
That conversation would normally start with the F word or at least in the first 4 or 5 words
Like I wasn't F--King speeding or F--k you I wasn't speeding or you can't give me a F--King ticket
Among many other conversations that they would beg for a citation.
