It is easy to draw that conclusion. However I worked with a 12 year old in 1993 who lit a fire. There was a sexual connection to his arson. This season also coincides with school holidays and kids these days are less regulated than previous generations. They do not consider consequences so readily. If anything I would be inclined to give more credence to a programming type response (via video games or an MK Ultra type manipulation) than payment,although that is a possibility for sure. There is of course the prospect of zealots setting fire to areas to prove climate change too.
