Mass Effect was already the story of how the galaxy was saved thanks to an unaccountable cop with unlimited jurisdiction and no limits on authority, succeeding despite his worst enemy: democratic bureaucracy trying to stop him from acting as he pleased.

Shit, the very first game has a Spectre go bad and almost doom the entire galaxy, and the problem is fixed not with addressing how Spectres probably shouldn't have a license to kill and no oversight, but by a good Spectre shooting the bad one.
