He's assuming all these emails are on an internal network. If that were the case it's likely the government gained access from a MU employee they leaned on (there are redacted MU conspirators from the indictment who are apparently not presently being charged meaning they may have been cooperating). What's more likely it seems is that these emails were sent internationally and the government (armed with a warrant hopefully) used their backdoors to access them. The arrests were apparently timed to conincide with many of the international employees being in NZ for KDC's birthday.
