If you did not consent to the photos or videos, then your boyfriend has violated your rights to privacy, and possibly committed a criiminal act in threatening to post them.
You can report him to the local police department, or if you are concerned because he is a former police officer, you can contact the local district attorney's office.
You may also contact a local attorney to bring a civil action against your ex.
Although I am not licensed in California, one of our associates is admitted to practice in California. I respond based on my general knowledge obtained from handling many similar situations over the last several years.
If he photographed you nude and videotaped you without your consent, he has violated your right to privacy. Some may argue that the location of such events make a difference. While perhaps they make some difference, it does not diminish the violation of your privacy. You may have a civil claim against him for intrusion upon seclusion. If he posts any of the material, you also may have a claim for public disclosure of private facts.
He may also have violated eavesdropping statutes depending on the content of the video.
You should speak to an attorney familiar with these issues such that a letter can be sent to him to attempt resolution prior to items being posted on the Internet (if they have not been already) and prior to filing litigation.
Even if items have been posted, an attorney with experience in this area may be able to secure removal of the items depending on the circumstances (though no guarantees can ever be made).
You definitely have claims. They need to be pursued strategically to protect your privacy.
The answers provided arise from general knowledge and experience. Thus, the information provided in the answers is intended to give a general response to a broad question asked. The answers DO NOT constitute specific legal advice. Additionally, the answers do not create an attorney-client relationship. Indeed, the answer is provided not knowing the individual who posted the query or the party interested in the answer. Again, the answer does not constitute specific legal advice as a complete assessment is needed to provide legal advice. Moreover, our firm requires signed engagement letters before providing specific legal advice. An individual should always consult an attorney privately who can ask specific questions and provide specific advice based upon the answers to the questions. An individual should not make independent decisions based on general answers to anonymous questions posted online. Consult an attorney before making any specific decisions regarding your own situation.
Avvo doesn't pay us for these responses, and I'm not your lawyer just because I answer this question or respond to any follow-up comments. If you want to hire me, please contact me. Otherwise, please don't expect a further response. We need an actual written agreement to form an attorney-client relationship. I'm only licensed in CA and you shouldn't rely on this answer, since each state has different laws, each situation is fact specific, and it's impossible to evaluate a legal problem without a comprehensive consultation and review of all the facts and documents at issue.
