Continuity mistake: When the group is escaping from the volcano, the whole sequence when they are trying to reach the boat shows different times of the day. At one point they are standing on the rocks watching men loading the dinosaurs into the boat with the sun directly behind them and behind the volcano, then as they are running to get in the truck, the sun is right above them. Once aboard the boat the sun appears to be again behind the island and the volcano. (00:47:10)
Continuity mistake: The Ford Explorer was laying out in the open where it was left after the events of Jurassic Park. But the huge tree that it fell out of was nowhere to be seen.
Continuity mistake: When Owen and Franklin are climbing in the truck, from the reverse angle Franklin is next to Owen, but from the front angle he's not. (00:51:00)
Continuity mistake: At the start we see Marine one approach the gates and they aren't even half way open. In the second shot they're open much wider. (00:01:40)
Answer: They were sold for the sole purpose of making hundreds of millions of dollars from the auction and future sales. The buyers had different reasons for wanting them: weaponizing them, for trophy hunting, private zoos, etc. The buyers' zeal in wanting such exotic animals overruled their sensibilities regarding how dangerous the dinosaurs were and the extreme conditions needed to manage them.
