This is one of those cases when the article title implies one thing, but the article tells a totally different story.

Man bursts into flames after being hit by Taser.

One might think "Oh my god, tasers are setting people on fire!"

Wellll, it turns out that the man in question had been sniffing petrol (gasoline), answered the door with an orange juice container holding petrol (and a lighter) in his hands, then threatened the police while holding the petrol.

Sounds like this could be a candidate for the Darwin Awards, and not a case of Tasers Gone Wild.
