New Jersey Governor Chris Christie has commuted the seven-year sentence of Brian Aitken, the man wrongfully convicted on firearms charges under that state’s draconian gun laws. Good.

While a full pardon seems more appropriate – the judge in this case should have given the jury instructions on the “moving exception” that protected Aitken – this is at least recognition of an injustice and relief for one man and his family.

The New Jersey state judicial system’s webpage describes the grand jury’s function as “a screening mechanism to protect citizens from unfounded charges.” That didn’t happen in this case. For more on this phenomenon, read this Cato Policy Analysis, “A Grand Façade: How the Grand Jury Was Captured by the Government.”
