To make Flint water crisis criminal charges stick against two licensed engineers employed by the state, Michigan’s attorney general will need to prove two things about Stephen Busch and Michael Prysby: that they made deliberate attempts to deceive the public about the lead levels in the city’s water and that they covered up or tried to cover up their deceptions or mistakes.
A third matter could prove just as important: that Busch and Prysby are the actual ones who directed and committed or covered up the alleged crimes.
