Is gun control dead? - Monday marks five years since the massacre at Virginia Tech, where a mentally ill student, Seung Hui Cho, used two handguns he had bought legally to kill 32 people and wound 25 others. Other than a relatively minor law to improve the national database used for background checks, no significant gun-control legislation followed that tragedy.  Since then, there have been several mass shootings, including additional school rampages and the attempted assassination last year of Rep. Gabrielle Giffords (D-Ariz.).Yet there remains little political will to reform this country’s flawed gun-safety rules — unless, of course, someone is proposing to make access to guns easier.
