Stefano Montanari and Antonietta Gatti are a husband-wife duo of Italian antivaccine "scientists" who like to use the electron microscope to find particulates in vaccines and try to scare people over them. Recently, Montanari was punched by an unknown assailant after having addressed the fascist group Casa Pound. Naturally, he thinks it's part of a government conspiracy to silence him.
A year ago, I wrote about some bad science from Italy from Stefano Montanari and Antonietta Gatti, in which an electron microscope was used and abused to claim that vaccines are contaminated with horrific "nanoparticles." A year later, Gatti and Montanari's homes, labs, and offices were raided and their computers seized in an investigation. Not surprisingly, the antivaccine movement has spun a conspiracy theory out of the raid. The real explanation is likely to be much less sinister.

You don't tug on Superman's cape, people.
