Can civilians buy military aircraft? Say one wanted to buy a retired F-14, or F-5, or a BAE Hawk. Could I do it?

Obviously this would mean stripping out radars, weapons, rwr, and any other sensitive equipment, but after this, would it be possible?

Is there some kind of procedure for this?

EDIT: What is the typical way aircraft are released for sale? Is it common?
You could, if the aircraft is available for sale somewhere, and there are no other legal compliance problems. Paul Allen has a nice collection of military aircraft at his Flying Heritage Collection, and there are certainly quite a few other people with both flyable and unflyable military aircraft. There are also private companies which will let you try out their planes, such as Australian Jet Adventures

Here is a web site which tracks military planes in private ownership around the world:
