Defense lawyers in a growing number of cases are raising questions about the motives of government lawyers who have brought charges against their clients. In court papers, they are citing the furor over the U.S. attorney dismissals as evidence that their cases may have been infected by politics.

Justice officials say those concerns are unfounded and constitute desperate measures by desperate defendants. But the affair has given defendants and their lawyers some new energy, which is complicating life for the prosecutors.

This is going to get worse.
