Ideally, the Federal Attorney General would be separately elected
Changing the structure of the national government is almost impossible given the current conditions, but even in the best of circumstances it's very difficult.
When it comes to "society," we need to distinguish between "the people"/society and "government." Government is created "by the people" so that we can be organized at the local-regional-state-national scale.
I argue that law, since it is the way that relations are constructed and mediated between people within society, belongs to the people more than to the "government" ("Executive Power vs. the will of the people and the DC Attorney General," 2015)
It's why I argued that the DC Attorney General should be popularly elected although I am somewhat disappointed by the results thus far.
Elected AGs disconnect "ownership" and more importantly control of the law from the Executive Branch.
As we can see from the Trump Administration, first in picking such a conservative as Jeff Sessions for Attorney General ("Jeff Sessions Confirmed as Attorney General, Capping Bitter Battle." New York Times), and now Trump's desire for the Justice Department to back off investigating Russian involvement in the 2016 Elections and culpability within the Trump campaign ("(President Trump and Jeff Sessions no longer on speaking terms," AOL), there is value to having "critical distance" between "the Justice Department" and the rest of the government, and this is in keeping with the concept that law, as a basic organizing instrument of society, belongs to the people first, and to elected officials second.
In short, I argue that the Attorney General of the US should be popularly elected, separately from the President. And the Department of Justice should be under the AG.
Some years ago I mentioned this once at an event held by Ralph Nader, and he understood the value of the suggestion, even if the main speaker did not.
I don't think Jeff Sessions ("Hearing Highlights: Sessions Questioned on Links to Xenophobia," NYT) could have been elected as Attorney General, given the various positions he holds on:
-- civil rights protections
-- voting restrictions
-- asset forfeiture
-- lengthening sentences regardless of case circumstances
-- private operation of prisons
It would be great for these kinds of matters to be discussed in the context of a campaign every four years.
To help increase voter turnout, I'd have this office be elected in the off-year cycle for national elections, not during the Presidential election cycle.
