Can Missouri Police officers Reduce your speeding ticket roadside with out committing perjury if they clock you at 75 miles per hour but write the ticket for 70 miles per hour in a 55 miles perhour zone. are they committing Perjury

Perjury? They are not under oath in a court of law. The statement on the citiation is for YOU, not them.
Reducing a speed ( quite helpful for you) or deciding to give a warning rather than a "hard copy" citation, deciding ( if they arrest you) to let someone come get your car rather than towing it, is within the bounds of "officer descretion".

They can reduce the spped, becaue they can testify that you were doing at least that amount of speed over the limit; they cannot increase over their observation supported by radar, becaus ethey have no proof of more speed than they did. It is not lying to say you were doing at least that speed.

Most people aregrateful if they knock it down.

There is no perjury unless they are in a court room. Police officers have "discretion". That means they can decide right then and there not to give you a ticket at all, or they can reduce the speed or number of infractions they ticket you for. This does not apply to Felonies and most misdemeanors. Therefore, remember.... it always helps to say your sorry! Sounds lame, but cops are people with emotions too...a smile and an apology will go a long way.

Actually, you can under oath in depositions also, and in legilative hearings and grand jurys.

Many law enforcement academies teach officers that the demeanor of the traffic offender should not be the deciding factor in whether to issue a citation or not; in fact many academies teach officers to already have their minds made up before they ever have face to face contact with the offender. In the interest of neutrality. Otherwise, all the cute girls might never get a citation and all the older wealthy men woudl. Bias for or against certain classes of people, in writing citations has long been a practice that requires discouragement. Though a bad attitude may provide you with some other citations or even being taken into custody in lieu of a (ROR) citation.

I forgot to add in my first response that the offender is free to tell the court he was actually doing an additional 5 miles an hour in the interest of accuracy.

Actually, you can never have your mind made up before you get the car and no one should either. There are too many variables to consider when it comes to issuing a citation and the reasons for it. But to answer your question, yes, you he/she can state a lower number of miles per hour.

I respectfully disagree, and the three state academys that I have lectured at all promote the same training. You deal with the "variables' with other citiations or other actions.

what variable would be significant enough to let oneperson go and the other not if they were both on radar at 20 over and no emergency situation existed? ( it was a rhetorical question)

NO this is not what I am trying to prove and I have not got a ticket. I am trying to show tha it is not just an ethical descission but it is also a legal one tht you cannot reduce a ticket just because you are a police officer you must be a judge or a procectutor to do this
