So, after 48 years can we now state that GCA of 68 is a failure? It has cost precious tax money, and civil liberties, to produce a system that fails to prevent or predict the violent crimes it was supposed to do. All government has ever done is to demand more concessions on civil rights to make an inoperable system worse. Its time to cut our loss and put GCA right next to the Volstead Act in the vault of useless laws.
