One thing, though: is it public knowledge that Lucius Malfoy had been a Death Eater?
I believe canon states that Lucius was tried in the post-Voldemort purges & Lucius’s defense was that he had been under the Imperius curse.
EDIT: The Harry Potter wikia, which ought to know, seems to agree: http://harrypotter.wikia.com/wiki/Lucius_Malfoy#First_Wizarding_War
