I think it should be a thing that if your business is hit with a molotov and the fire rages out of control and kills people, you should probably be forced to shut down for a set period of time (24-48 hours etc).
My thoughts behind this, all realism aside (Because your spot would be a charred room sized ashtray) is that if you are having issues with business owners (They are not paying you protection, you just don't like them too much, their only rated 2/5 stars on yelp) molotoving and bombing their building should be an RP creating and efficient way of hitting them instead of the typical killing/beating scenario.
Also, I know, this could be abused heavily. I get it, but that's what discussions are for to take an idea and mold it to fit (or not to fit)
