FHP Charges Tiger With Careless Driving; Case Closed?

One thing really leaps out from today's Florida Highway Patrol announcement of Tiger's $164 fine and four point addition to his drivers license record.

The FHP is not pursing criminal charges in this matter, nor is there any testimony or other evidence to support additional charges of any kind. After reviewing the evidence available to us, and in consultation with the Office of State Attorney Lawson Lamar, it was determined that there was insufficient evidence available to issue a subpoena for additional medical information that may exist in this case. We cannot speak to the existence of any blood evidence, nor are there claims of domestic violence by any individual.

Based on what we learned earlier today, state law does not require a "claim" of domestic violence for an agency to purse an investigation and possible charges. Was this because it's out of the FHP's jurisdiction to investigate domestic violence, above their pay grade or just something they chose not to pursue?
