Now, come on now. I can't imagine the federal government ever ignoring Fifth Amendment restrictions about the sanctity of private property for individuals.
Oh, wait a minute, they did just that with Kelo.
But I'm SURE that was just an isolated incident! Government would NEVER abuse the power to dictate private property rights, other than that!
What property rights? Just try not paying your property taxes and see who comes to take your property. The SCOTUS just codified what was already common knowledge.
