Things that should never have happened

I didn't really want to put these in the same post as the previous. From BBC: Burma migrants suffocate in lorry:

More than 50 Burmese illegal migrants have suffocated in the back of a lorry taking them into southern Thailand, Thai police say.

The 54 migrants were found dead inside the packed container lorry after dozens more managed to escape from the vehicle and flag down police.

Police said the migrants had suffocated after the air-conditioning failed.

They had been packed into an airtight lorry for the journey to the resort island of Phuket, Col Kraithong Chanthongbai said, but the ventilation failed.

"When police got to the scene, they found that 54 of the workers were already dead in the packed container truck," the Associated Press news agency quoted him as saying.

Twenty-one other workers were taken to hospital, he said. As many as 46 other workers did not require hospital treatment and were detained.

The driver of the lorry fled the scene.

No, this should never have happened.
