President Obama is expected to announce how his administration is going to prosecute prisoners for war crimes and perhaps other terrorist offenses. Instead of civilian court, courts-martial, or new “national security courts,” Obama has apparently decided to embrace George W. Bush’s system of special military tribunals, but with some “modifications.”

Glenn Greenwald slams Obama for seeking to create a “gentler” tribunal system and urges liberals to hold Obama to the same standards that were applied to Bush:

What makes military commissions so pernicious is that they signal that anytime the government wants to imprison people but can’t obtain convictions under our normal system of justice, we’ll just create a brand new system that diminishes due process just enough to ensure that the government wins. It tells the world that we don’t trust our own justice system, that we’re willing to use sham trials to imprison people for life or even execute them, and that what Bush did in perverting American justice was not fundamentally or radically wrong, but just was in need of a little tweaking. Along with warrantless eavesdropping, indefinite detention, extreme secrecy doctrines, concealment of torture evidence, rendition, and blocking judicial review of executive lawbreaking, one can now add Bush’s military commission system, albeit in modified form, to the growing list of despised Bush Terrorism policies that are now policies of Barack Obama.

Greenwald is right. The primary issue is not due process. The tribunals might ultimately be “fair” and “unbiased” in some broad sense, but where in the Constitution does it say that the president (or Congress) can create a newfangled court system to prosecute, incarcerate, and execute prisoners?
