Pentagon officials say 20,000 U.S. military members will be in the country to deal with domestic catastrophes, according to this report in The Washington Post. That’s concerning, considering President-elect Obama’s rather vague comments on a civilian security force.

From the article:

The long-planned shift in the Defense Department’s role in homeland security was recently backed with funding and troop commitments after years of prodding by Congress and outside experts, defense analysts said.

There are critics of the change, in the military and among civil liberties groups and libertarians who express concern that the new homeland emphasis threatens to strain the military and possibly undermine the Posse Comitatus Act, a 130-year-old federal law restricting the military’s role in domestic law enforcement.

But the Bush administration and some in Congress have pushed for a heightened homeland military role since the middle of this decade, saying the greatest domestic threat is terrorists exploiting the proliferation of weapons of mass destruction.
