Lol, you absolutely can not do that. That is sooo crazy. You actually have to encourage your employees to speak up when they see something is illegal. Of course everyone knows don't ever put that in email
The inherent problem with Googlers defending Google, beyond the obvious conflict of interest of expressing views about the company that writes your paycheck, is that Googlers expect us to trust them that the internal info they can't share isn't suspect.
If you can't share what's actually going on internally, you shouldn't be defending it. Let the case happen, with any luck these internal presentations, policies, and memos will end up in the public record, and we'll all be able to see what's really going on.
