This may be why Tiger declined to speak to law enforcement. Florida domestic violence statute:
(3) Whenever a law enforcement officer determines upon probable cause that an act of domestic violence has been committed within the jurisdiction the officer may arrest the person or persons suspected of its commission and charge such person or persons with the appropriate crime. The decision to arrest and charge shall not require consent of the victim or consideration of the relationship of the parties.
I do believe Elin took a golf club to Tiger and his car. If she were to be charged and convicted of a felony charge, and is not a US citizen, she would be deported to her home country.
Similiar to the Heene's in Colorado, that is why the husband pleaded to a felony, and his wife a misdemeanor. She is not a US citizen and would have gone back to Japan.
I do feel Tiger should be given his privacy, there have been far worse cases of athletes taking a bad turn.
Michael Vick comes to mind, and he's back with the NFL, although he lost his endorsements.
Steve McNair was not as fortunate, in his situation, when it came to straying from his wife.
Not to mention all the other sports athletes who have had their share of bad publicity, and in some cases they recover, and in others, their careers ended.
Only time will tell with Tiger.
