Walter Williams' new op-ed on Gun Control

Walter has a useful piece here:

Every time there's a highly publicized shooting, out go the cries for stricter gun control laws, and it was no different with the recent murder of Philadelphia Police Sgt. Stephen Liczbinski. Pennsylvania Gov. Ed Rendell and Philadelphia Mayor Michael Nutter, in a letter to the state congressional delegation demanding reenactment of the federal assault weapon ban, said, "Passing this legislation will go a long way to protecting those who put their lives on the line every day for us. … There is no excuse to do otherwise." . . . .
