Regarding the Opinion page article "Intercept Migrating Guns," Sept. 10: The author forgets that there is a law of supply and demand. Nothing prevents one from driving to New York, Chicago, or wherever to sell a gun on the street where there is a great demand. A gun is a forbidden fruit in these places, and when the fruit is forbidden there is a great demand for it. Prohibition was also a federal law, but everyone, including law enforcement itself violated it, and that is what brought its demise. Federal
law or not, a criminal will find many ways to violate it, especially now when jails are bulging at the seams and early release of inmates is a common occurrence. Igor deLissovoy, Tampa, Fla.
