@RS:  Obviously?  LOL!  Sorry to disappoint you RS.  I live in a building with a sprinkler system.  I can make the same argument that you are (RS is more concerned with RS's pocketbook than human life) for residential homeowners that aren't currently required to have sprinkler systems in their homes that would oppose a law to make it mandatory which you seem to be a member of.  If I am wrong and you support mandatory sprinklers for all building structures (low-rise, high-rise, single/two story houses, etc), then where is your outrage that all structures aren't required to have sprinkler systems?  Let's hear your explanation.
