You make it appear that you were super vigilant, and you probably were. You built a privacy wall and listened. I'm curious what conflicts that you have had with that neighbor in the past. It would be a "he said vs. she/she said" without a photo. The neighbor may have been plotting how to get you or made complaints unsuccessfully in the past. He then, may have been told to have a picture as proof. HE would have to have been watching pretty darn hard to see you. He may have been hiding and creeping to get that picture, and assuming that you were nude. In other words you may have been stalked by a hidden voyeur. That may be illegal in your state. You certainly were no "reckless" nor showed genitals. No photo was produced, only hearsay.
The guy is out to get you, feels powerless, he wants to win his little war and you have committed the offense of denying him control in his kingdom and within his "right," so may continue his "fight." Personally, I'd be very pissed and looking for an attorney for a civil solution to bite him in the butt.
So, you broke no law, yet you have been given a citation as if you stood out front and flicked your finger at this shitty neighbor across the street. Yo have been civil, he is obviously provable out to get you. He could be seen in court as malicious.
Now, was there an actual picture, or did the a-hole just claim that. There should be no picture of the required genitals. You took extrodinary measures to keep your privacy and had a reasonable expectation of that.
You are innocent. You would win in court. Could these be construed as false charges? False allegations? Get the guy back to burn his fingers for lying to a police officer about the existence of a dated picture? Sue to have him pay for your court costs (usually much less than). I don't know much about "Texas deferred adjudication" but it requires some hassle to get it to go away from your record. You still have the problem of dealing with this vindictive a-hole across the street. Do you stick to the backyard, or do you communicate, or give 'em a whack of some kind to teach him to lay off? Do you have a feud? How can you find a way to get him to lay off of your privacy?
My neighbors never produced the picture that they claimed to have. I suspect that it was a cell phone pic in an entirely different place that their kid went to a lot of trouble to get, otherwise it was a case of them laying in wait hidden in bushes to catch us with a high powered camera. People lie.
It could be one of those cases where the cop decides that he wants to do something even though no law has been broken. A charge is filed, the victim sweats for a few months waiting, then the cop doesn't show up and it is thrown out of court. There is expense and no justice other than for the cop that makes his own laws and executes them without trail. You have a right to meet your accuser. You have a right to see that evidence, the picture. The neighbor could lie under oath, and they will if cornered. The neighbor could not want to get that involved. Depends on the personality. It may go away.
I'm kind of principled at times and demand justice out of the courts. I don't like to compromise my rights, but I have been practical in divorce, a civil matter. I don't like to spend my energies fighting and would rather be left alone, but sometimes I get wrapped up in things and go all out, enjoying the memories and feeling good about it. I never know where I'm going to draw the line. I assume that you live in a flat area. Maybe you need to spend the court expense money on a nice tall privacy wall?
The cop and the neighbor are not reasonable and are pushing you where they have no right to, if the facts that you have given are correct, nothing left out. Please, let us know what happens, vent, or maybe give us a good feeling about justice. The NAC may have some practical advice and a good attorney in your area. False charges by a cop is a very serious matter for us all. What does "disorderly conduct - offensive gesture" supposed to mean, anyway? I don't see it in anything that you have presented. What does the police report say? I see no evidence, almost as if it was pulled out of the air. If there s nothing there then it is a waste of the courts time and resources. It is also one legal strike against you, if this a-hole is further emboldened to complicate your life, saying that you did this or that, as some of my previous neighbors did to everyone.
