He pled guilty in his last serious criminal case.
They're actually obligated to. Virginia uses a grid system where (unless the statute requires a specific sentence) the severity of the crime determines a general range of sentences, and then prior criminal history bumps it up depending on its severity, giving a modified range, and then the court generally chooses a sentence within that range. Although the judge can choose to deviate from that range within the statutory range, the judge must provide factual reasoning (if there is a jury based on facts before the jury) in order to sentence outside the range.
And there's a bunch of other arcane bullshit. I'm not sure if this is the correct worksheet, but there are worksheets for most crimes and types of crime.
This is a class 1 misdemeanor, which would have a statutory penalty of "confinement in jail for not more than twelve months and a fine of not more than $2,500, either or both."
As ugly as that worksheet is, they also have an online system called SWIFT but you need an account, and you need to be an attorney or other court personnel to qualify for one, and I don't have it in me to create a fake account just to guess what kind of sentence Gunt gets.
There are two statutes, but the first is creating such images without consent, and the second is disseminating them without consent when they were created with the expectation of privacy. Apparently, Faith consented to the video being made, but not to it being disseminated, so he's only charged with that.
