Let's take our emotions out of the picture and reflect on WHY the FWC and Martin County Sheriff's haven't filed ANY charges. Could it be the evidence says nothing criminal occurred? You might want to go back to the statements made by the divers the evening of the accident where
they stated the boat was passing by and veered off course suddenly. Those statements
by the divers certainly support the story of a spun prop hub or steering failure.
