Hello and thank you for contacting JustAnswer. My name is Michael; I look forward to assisting you today.
By continuing, you acknowledge that I am not providing legal advice and can only comment on the law in general.
When someone over 18 sends a nude image to someone else over 18, they are usually not committing a crime. They are both consenting adults. If you were to accidentally send a nude image to a random stranger over the age of 18, I seriously doubt you could be charged with a crime. One possible outcome if that you could be charged with harassment, but harassment statutes typically require a series or pattern of harassing actions. One action, made in error, would not qualify for harassment in my opinion. The only other scenario to consider is whether you sent a nude image to someone under 18 on accident. In that case, I could see charges - possibly - for something like contributing to the delinquency of a minor or cyberstalking or luring or something along that nature. Again though, if you can show it went to a random number on accident, I don't see the State of Maryland being able to show you had the mens rea - otherwise known as "intent" - to commit a crime.
