If I was that officer, I would get an attorney and file a large lawsuit against that liar who could have cost that cop his job. Make an example out of him and make others think twice about making false accusations.
While working patrol in the 70's and 80's, I got so tired of the outright lies filed by idiots like that. I used my own funds to purchase a mini tape recorder that I carried in my shirt pocket. It was turned on and voice activated everytime I made contact with any citizen.
Saved me several times from false accusations and several times used in court to convict persons who lied on the stand under oath.
