Fun fact: the Philadelphia Police Department also likes starting fires. 35 years ago, they used plastic explosives to blow up the house of the MOVE group, killing most of the people inside (including five children). Instead of putting out the fires, the city allowed a good chunk of the predominantly black working class neighborhood to burn to the ground. The city did get sued in 2005 in a civil trial for burning down the houses, but no one from the city government has been criminally charged for the attack. That seems like the kind of terrorist act that the FBI would investigate, but I guess they have different priorities.
