Unpossible!

The Chicago Sun-Times reports today that an Uptown man was arrrested yesterday after he made "unspecified threats" to the Willis Tower.

..investigators found 20 guns, several pounds of gunpowder and two grenades in his apartment.

But later Monday, police said that “there was no overt threat made,” and that the 60-year-old renter had been taken a facility for a mental evaluation.

Guns? Grenades? Being as this happened in the Daley-run City of Chicago, the only word that comes to mind is unpossible!
