It is possible. How has the punishment for being caught with a bonfire in a place where it is not permitted changed over the last number of decades?

Or is it just the reduction in lead? That is what is oft cited as the reason for why crime rates have dropped substantially over a very similar period. Which may leave my framing of the kids being fearful to be a little off, rather the reduction in lead would suggest that they have better impulse control, but I am sure you can understand that the intent there is the same either way.
