Earlier quoted context omitted.
The Swartz case aside, nobody likes the DOJ. Liberals don't like them because they're tasked with defending laws like DOMA (until recently), drug laws, etc, and people like John Yoo, etc, that are unpopular with their contingent. Conservatives don't like them because they are tasked with defending laws like the Sherman Act, etc, that are unpopular with their contingent. But each side likes the laws that are unpopular…
There are some pretty serious oversimplifications there. I can "like" an office or department even if its current inhabitant is doing something I don't like. For obvious reasons, this is doubly true when we're talking about an office inhabited by political appointees.
To a liberal, the DOJ is in the abstract the agency that enforces anti-trust laws or the like against big companies. But the actual DOJ is the one going after people growing weed. To a conservative, the DOJ in the abstract is the agency that goes after drug traffickers. But the actual DOJ is the one meddling in mergers.
