Off course they are lying. It is what they do. In 2013 when 47 people were killed by the oil tank car explosion in Lac Megantic, we all heard about it. When at practically the same time a mile of oil pipeline exploded in downtown Qingdao, China killing 62 people, nobody heard about it. Here are two links, one showing just how bad an oil pipeline explosion can be in a downtown area, and the other describing what steps have been taken in the aftermath.

The second link also includes reference to a gas explosion in 2003 which killed 243. The role of human error was well documented. Everyone who says all these volatile fuels are safe conveniently forgets human error. Incidentally, which town was wiped out and when?
