As I live in the hills, surrounded by forests and reserves in one of the most arid countries on the planet, arsonists are our worst nightmare. I think the penalties here are being revisited, mainly because of the potential for huge losses of property and life. As you may have seen on international news footage...we have had some devastating fires over the past 2 years, so very sad to see people lose loved ones and neighbours.
Hope you feel better soon, and I would be keeping coat/keys etc. close by in case this happens again.
