Lots of good advice....
Last Spring as we were driving through Astoria, Oregon, we saw a white shiny pickup
parked on the street with a HUGE sign on the tailgate that said something like this: (Pretty close to the original statement which started with an apology like to the court ) and ended up with
"OFFICER Xs()*(&* IS A LIAR IN COURT"

We nearly ran off the road....
Always be respectful and don't send out a lot
of negative body language.
Good luck.....
