I'm assuming the owner of the units wasn't around for it at the time so there wasn't the backlash while saving the whole rest of a community from the fire spreading.
Don't ever discredit a certain percentage of humans urge to destroy and break things, especially in a drunken rage. We spend a great deal of effort keeping people well socialized, despite plenty of pent up anger.
That's why we have professionally trained police and firemen now. Things are always improving for the better.
