Injustice in 1605?

BBC News: Free the Gunpowder Plot One.

Was one of the Gunpowder Plotters an innocent victim of circumstance? As effigies of Guy Fawkes again go up in flames, is it time to rectify a 400-year-old miscarriage of justice?

After the failed attempt to blow up Parliament in November 1605, Henry Garnet, a Jesuit priest, was hanged, drawn and quartered, and his parboiled head displayed on London Bridge.

A 17th Century book describing the execution of this "barbarous traitor" sold at auction last year, with the unique selling point that its cover was allegedly made from the executed man's skin. But was the subject of this text really guilty?  On the day when the UK marks the anniversary of its most famous attempted coup, a historian is asking some awkward questions about one of those executed for his role in the Gunpowder Plot.

We will never truly know whether Garnet was innocent or not.  The Gunpowder Plot Society isn't convinced.  They say that Garnet knew of the plot and did nothing to prevent it, making him culpable.  Garnet was not one of the thirteen plotters but the Gunpower Plot Society has a profile of him, along with everyone else involved or touched by the plot and an excellent overview of the plot itself.

I'm not convinced Garnet was innocent.
