Dr. Kevin Ronan's got a lot of explaining to do. The Navy commander currently faces a number of charges stemming from videos he allegedly made of cadets having sex. And, as part of the trial, the prosecutors have successfully submitted gay porn as evidence.

Gay pornography found on the computer of a Navy doctor can be submitted as evidence in his trial on charges that he made secret video recordings of Naval Academy midshipmen having sex in his Annapolis home, a military judge ruled yesterday in a decision that could put the physician's career in jeopardy.

Ronan's defense lawyer attempted to thwart the move by claiming that one of Ronan's charges may have downloaded the porn. Prosecutors, however, also pointed to what appears to be Ronan's account with gay sex star Brent Everett's website. Ronan claims someone stole his identity and started the account, which may be the worst defense in history.

Defense lawyers claim that such evidence will undoubtedly lead to questions of Ronan's sexuality, which could lead to his dishonorable discharge. William Ferris told the judge:

The effect of this is going to be to suggest, 'This is a bad person, he's got homosexual tendencies, and we certainly don't want him in the Navy.

Ronan's accused of taping one cadet having sex with his girlfriend and of recording another masturbating. The porn, the judge says, will could prove Ronan's "possible need" to watch men having sex.
