You really can't be so naive as to equate DOMA with hundreds of thousand of unknown laws, or are you? So that's your reasoning? It was just a matter of not having the money and manpower? I'm going to make the argument that DOMA and immigration laws are a little more prominent than most of the others. Oh, and the President still can't pick and choose laws to enforce. Especially laws of that much importance.it only makes sense that the President would direct the Justice department to prioritize the enforcement of certain laws over others. There's no such thing as enforcing all of them equally because the nation doesn't have anything close to the money or manpower to do so. When you have an estimated figure as high as 300,000 laws (though again keep in mind that's just a mad estimate -- nobody knows the real number), at that point it actually makes sense to say something like "You know what? This law here is ****ing stupid. I'm telling the Justice Department to pursue these other laws instead."
So let me emphasize: if the Justice Department had sufficient manpower and enforced every Federal law on the books, everyone reading this would be guilty and in Federal prison.
