Masks are being widely worn this week as a hedge against contracting the new coronavirus. You can make your own if handy with needles and the materials, buy packets of them on the Internet, or fashion one out of a whole T-shirt.

This is as good a time as any to put in another plug for the 2018 book 9/11 Unmasked: An International Review Panel Investigation, by David Ray Griffin and Elizabeth Woodworth (Olive Branch Press).

From a squib on the back: “Many Americans have been embarrassed by the Trump presidency. But Americans should also be embarrassed by the fact that this country’s foreign policy since 2001, which has resulted in millions of deaths, has been based on a complex deception.

“9/11 Unmasked is the result of a six-year investigation by an international review panel, which has provided 51 points illustrating the problematic status of all the major claims in the official account of the 9/11 attacks, some of which are obviously false. Most dramatically, the official account of the destruction of the Twin Towers and World Trade Center 7 could not possibly be true, unless the laws of physics were suspended that day. But other claims made by the official account—including that the 9/11 planes were taken over by al-Qaeda hijackers, that one of those hijackers flew his plane into the Pentagon, and that passengers on the planes telephoned people on the ground—are also demonstrably false.”

One may purchase a copy online and have it delivered within a week. Why not do so? It may arrive before one’s order of masks.
