The use of commercial litigation and regulatory law to achieve progressive political goals is by now familiar: If an oil company opposes global-warming initiatives, that isn’t politics but “securities fraud,” as far as Democrats are concerned; if conservative activists want to show a film critical of Hillary Rodham Clinton in the lead-up to a presidential election, that isn’t politics but a “campaign-finance violation,” as far as Democrats are concerned.

This lawsuit happens against the background of progressive demands that certain political views be criminalized.

There are two kinds of opportunism at work here: One is purely financial, the prospect of getting a big payday that sets the stage for additional big paydays in the future as the ghouls go from manufacturer to manufacturer and crime scene to crime scene collecting billions of dollars as they go. The second is political opportunism, the attempt to establish the precedent that failing to go along with the progressive political agenda makes one an enemy of the state, subject to political sanction and criminal prosecution.

The crime here was committed by Adam Lanza. But he isn’t the one with the money, and there’s no political juice in going after him.
