Justice isn't a legal concept. It also isn't anything real, like a liter bottle of Coca-Cola or a one-bedroom co-op in Manhattan listed for $550,000. Instead it's an abstraction, fleshed out uniquely in the mind of each human being.
If that human being is adept with digital communications he or she can achieve justice without the intervention of a lawyer. That is called "public shaming." It began, as Eric Randall points out in Boston Daily with the Puritans in Massachusetts. Nathaniel Hawthorne captured that ethos in his novel "The Scarlet Letter."
Today, the process is accelerated with Twitter's short form. Within minutes one's own notion of justice can be achieved. And, really, isn't that all we want (unless you're into slip and fall, libel and emotional-trauma lawsuits).
Why bother doing a deep dive in legalities on anything? Not if what you want is justice, not damages, not the theatre of the courtroom, not putting the miscreant in the slammer.
This could eliminate the need for plenty of lawyers. In their place would be $10-an-hour Millennials who are fast and furious on social media. Twitter would just be the start.
A side effect is that people might become more careful how they treat other people. Ever since I entered social media as a syndicated blogger a decade ago I have received much more respect.
