Thats an easy one. Chicago is a liberal hell hole that decides the fate of the rest of the state. The reason they have foil cards are because they want to make it difficult and frustrating to get a gun. They hope this will discourage people, and result in deminished gun ownership. The reason it takes so long is because they don't want you to get a gun. They hope that by the time you actually get it (if you ever do), you will have given up on getting a gun.
My advice, get as many guns as you can, and encourage everyone you know to do the same. It will be like a big middle finger to them.
