Before you accuse someone of perjury your need to consider a couple of things.
First, every court in the nation has standard instructions that are given to jurors when it comes to considering witness testimony. The exact language may vary from state to state, but essentially the court's view on evaluating testimony is as follows:
Sometimes a witness may say something that is not consistent with something else he or she said. Sometimes different witnesses will give different versions of what happened. People often forget things or make mistakes in what they remember. Also, two people might see the same event but remember it differently. You may consider these differences, but do not decide that testimony is untrue just because it differs from other testimony.
In other words, just because the officer perceived a portion of your event differently than you doesn’t mean he perjured himself.
Additionally, if you believe it appropriate to accuse the officer of perjury because his testimony differed from yours, then all things being equal, it is just as appropriate for him to accuse you of perjury because your testimony differed from his.
