Part of the problem there is that the liberals have been allowed to define everything out of the word treason. Just try to get a liberal to define what is treason without defining it as Bush/Cheney.
It might be worth reviving. We definitely need treason laws to protect our country. But let's start by jailing the reporters, a remedy that has already proven effective in the Plame case. Also their editors, who presumably authorized these stories and, if what they were saying in the Miller case is true, were told the names of the sources.
