OK, first, let me clear things up. There's only 1 Sheriff in each county, and I'm not him. Under him are the deputies, from Captains, Lieutenants, Sargents, Corporals and no striped deputies. Any one of those can stop you and write citations. Under all of them are a force of sworn officers called PSO's (Public Service Officers). That's me. I don't engage in traffic stops or apprehending suspects. I do write citations after the fact, like to someone who caused a traffic crash (they're called crashes, not accidents) and for violations of the non-moving traffic code like dark tinted windows or illegal taillights plus illegal parking. I respond to acts of vandalism and larceny at a home or business. Escort duty, found and lost property, traffic control and a host of other duties.
I can and do receive traffic citations (only 1 in the last 10 years) from a State Trooper (those guys have no sense of humor), but have received numerous "acts of kindness" from other in-state and out-of-state officers for traveling above the speed limit.
There is NO "quota" of citations that the Sheriff's office has to fill so a lot of discretion can be given by any officer that stops you so watch the way you respond when stopped. Discretion goes away if your doing 80 in a 50mph zone, school zone or construction zone.
Everybody has bad days, even officers so you might not get out of a citation even going 5 over the limit, and of course there are cities and towns that depend on revenue from citations so it's pretty certain your going to be feeding the town part of its income when you speed thru them.
Most LEOs (Law Enforcement Officers) are car guys so they appreciate a good looking car, but not someone showing off and putting people at risk in that same car, and yes, some women tend to get away with a bit more than men ....LEO's are only human.
Now, in the northern states, it's different. The POLICE have all the law enforcement duties and the Sheriff's department handle warrants and other duties not pertaining to traffic.
We used to have a POLICE department in the two largest towns here in my county, and I was a PSA (Public Service Aide) for one of them. Then the towns found out that it was cheaper to let the Sheriff's office take over law enforcement duties and disbanded the Police department. Most Officers were picked up by the Sheriff's department, including me.
