This one got by me somehow, but at least the ending is better than in most cases.
From
The St Petersburg Times
The angler recognized the boat roaring past him in the manatee refuge. It belonged to one of his neighbors in Brevard County. It was going much too fast.
Then the boat slammed into a manatee, a collision so violent that the boat jumped out of the water. The manatee's fluke was still sticking up from behind the motor. The manatee thrashed wildly as blood spread across the rippling waves.
The boat sped away. The angler, horrified, called the authorities to report what his neighbor had done. It turned out this wasn't the first time he had violated the speed rules.
