Saw a slightly different version awhile ago. As usual, it appears the government is using a howitzer to swat a fly. Yes, it appears the lady did start the fire, but not intentionally. She has been having marital difficulties and she burned a letter from her estranged husband. Unfortunately, although she thought the scraps were all out -- they weren't.
So they are charging her with arson. God save the queen, what a bunch of idiots. Arson is for when someone intentionally tries to burn something down. Burning a letter and failing to completely extinguish the embers is not arson, it's an accident. Yes, a very serious and costly accident, but an accident nonetheless. There are probably several lesser charges she could and should be charged with, but arson?
I love my country but I fear my government.
