Iโm not being a realist here (โthere are no sure betsโ) nor is this mere nihilism (โyou will never be safe!โ).
There is no such thing as security in the abstract.You cannot be generically secureโโโyou can only be secure from something. A sprinkler system increases your security from fires, but not burglars. Not only that, but a sprinkler system reduces your security from water-damage.
