My question involves an easement in the state of: Texas

We live on a Private Road that has been listed as Private road through the proper channels. We have noticed a police officer parked on the private road. We were told that since it is a private road the police could not patrol this particular road because it was private. We were wondering if this was true and what actions we could take to keep the officers from parking on our road in front of our house for no apparent reason.
