Yes, there's plenty of jobs that you can land with a law degree, and a literal 10s google search will tell you.
From my understanding, intelligence agencies do hire lawyers, since they need to know what is/isn't legal (though they tend to be on the blurry side of things, e.g. ASIO doesn't like whistleblowers revealing illegal operations). A degree in international crime or international policy, or even in fields like linguistics, would be favourable in the eyes of an intelligence agency. As for social justice...yeah nah they're not gonna care about that lol.
