It started with an argument, the kind of argument you might see at any nightclub or bar on any given night. A man tried to get his ex-girlfriend to give him another chance. She told him no. Angry, he made a grab for her. One of the bouncers saw, and the man ended up kicked out on the street. But within a half an hour he'd return -- this time with a gallon jug of gasoline and a pair of matches.
