If law was as simple as reading what's written down, then what are all the lawyers and courts for. There is a lot of interpretation going on.

But really I was referring to the process of how the laws are formed in the first place. A lot of the time they start out under-specified, and as abuses emerge we make more concrete laws using our new understanding. Of course the latter part usually leads to a lot of discussion and resistance because of the collateral damage any new law causes by being slightly broader than necessary. Which is a major reason many industries self-regulate in the attempt to make explicit laws unnecessary.
