hmm, how many hi-rises(75' or higher) without sprinklers ? , 100?, 1000? 10,000?.....how many fires since 1975 ? ...,how many that resulted in death due to fire?.....as I said before, the tragic(unexpected) deaths of these 3 people is very sad and very possibly could have been prevented but with the knee-jerk reactions and Monday morning qb's....you could also make an argument that if the speed limit was mandated to a maximum of 20mph on the hwy's and freeway's that auto accidents would disappear.
