So, lemme see-
The economy is bad. Furs, being a luxury item, probably aren't selling all that well.
A bunch of dipsticks comes along and tries to "hurt" a furrier by burning his furs and property. Insurance pays him off. In effect, he has netted guarranteed sales. Without his merchandise on the market his competetors who sell furs can demand higher prices for their goods. And, of course, more animals will be trapped to provide replacement stock for the guy who had his furs burned.
Yeah. I'm flabbergasted by the sheer genius the arsonists displayed.
