are there any limits to presidential power power left? (pt. 2)

and as if the ever-expanding power of the executive wasn't bad enough, now this. From the July 24 New York Times:

Top Bush administration officials in 2002 debated testing the Constitution by sending American troops into the suburbs of Buffalo to arrest a group of men suspected of plotting with Al Qaeda, according to former administration officials.

Of course, there's a minor wrinkle in this plan:

A decision to dispatch troops into the streets to make arrests has few precedents in American history, as both the Constitution and subsequent laws restrict the military from being used to conduct domestic raids and seize property.

The Fourth Amendment bans “unreasonable” searches and seizures without probable cause. And the Posse Comitatus Act of 1878 generally prohibits the military from acting in a law enforcement capacity.In the discussions, Mr. Cheney and others cited an Oct. 23, 2001, memorandum from the Justice Department that, using a broad interpretation of presidential authority, argued that the domestic use of the military against Al Qaeda would be legal because it served a national security, rather than a law enforcement, purpose.

Sound familiar?
