Mel Gibson’s rants caught on tape, which have now been subpoenaed by the police, might be enough evidence for him to be charged for terrorist threats, mayhem, battery and hate crimes — and he could be facing more than eight years in jail, say lawyers.

Mel Gibson’s brutal and frightening telephone rants toward his now ex-girlfriend Oksana Girgorieva were caught on tape — and three lawyers tell HollywoodLife.com the 54-year-old actor is facing serious charges — including domestic abuse, terrorism, mayhem and hate crimes, which could mean eight years or more in jail.

“It’s as serious admission of guilt as I’ve ever heard,” divorce lawyer and author Vikki Ziegler told HollywoodLife.com after listening to Mel’s second rant, which leaked July 12. “In California, they are going to prove it as a felon, if they can prove it’s him. I think he has some major headaches — felony charges, they’ll take away his gun, fines, jail time, losing custody.”

Lawyer and sexual violence expert, Wendy Murphy, agrees with Ziegler that Mel is guilty of serious crimes.

“Oh my god. I can’t even tell you. It scares me — and I’m pretty tough,” Murphy said. “There are so many things, but not the least of which of was he basically he teared into her becasue she wouldn’t give him a blow job. She said, ‘I’m exhausted’ and he freaked out.”

Not only does Mel admit to having punched Oksana in the face and breaking her teeth, he threatens to kill her twice and uses verbally and sexually abusive language. All three lawyers — Zieglar, Murphy and Los Angeles-based criminal defense attorney Steve Cron — think the Braveheart actor is facing major criminal charges, including, but not limited to, the following:

Criminal Threat and Battery:

“A criminal threat is basically a threat that is enough to induce fear in the mind of the believer that there is the possibility of an imminent assault. When she’s saying, ‘You just hit me,’ that’s battery. Saying, ‘I’m going to kill you,’ that’s a criminal threat.” — Cron

Hate Crime:

“He should be charged for a hate crime — some people may say you can’t base it on being against women — but the truth is this guy has not just hate, but the kind of hate that fuels rage. Also, because of the hate crime’s nature, any possible misdeamnor — like battery — would automatically be charged as a felony.” — Murphy

Domestic Violence:

“He admitted clearly punching her in the mouth and in my opinion, admitted to knocking her teeth out or at least breaking them. His admission was non-denial alongside, ‘You deserved it.’ If someone accused me of knocking my teeth out, I would say, ‘No I wouldn’t.’” — Murphy

Mayhem:

“He potentially knocked out or broke her teeth, which is a very serious felony called mayhem — it carries up to eight years in state prison. It’s much more [serious] than a bar brawl or even a [typical fight].” — Murphy

Loss of Custody Of Lucia:

“He has huge problems with custody. If you commit domestic violence, the family court asks for disclosures of five years worth of stuff, so any time in that five year period, the court is almost obligated to present a presummption against your custody. Forget sole custody, if there’s been domestic violence.” — Murphy

Mel’s Defense(less):

“It’s against the law to tape record somebody without their consent…unless it’s for the purpose to document the crime.” — Cron

“When anything’s on audio, you’re in BIG trouble. They can try to mitigate by saying she has a history with emotional issues, if they can prove she’s unstable.” — Ziegler

“You should have been medicated. You cannot have moments of insanity and then come back to sanity. He’s not delusional.” — Ziegler

“Nobody in the court has much sympathy when someone has a drinking problem and they let it get the best of them.” — Cron

The Los Angeles Sheriff’s Dept. has launched an investigation and has issued a subpoena to attain the audiotapes of the rants. As HollywoodLife.com first reported, The Los Angeles Department of Children and Family Services has already begun an investigation to determine whether or not Mel and Oksana are fit parents.
