There is a sharp schism between subscription journalism and ad-supported content. For the most part, the former are doing investigatory work. For the most part, the latter are not.
Well, the counterargument is that it's indicative of taking actions that you know will be met with general criticism and can be justified.
For politicians I'm going to guess that a lot of stuff they don't want on record is specifically related to their self-betterment by somehow (even minorly) compromising their duty.
A policy of staying off-record by default is not an unreasonable countermeasure to that problem.
An email that, for example, threatens bad performance reviews if an employee doesn't show up at an optional after-hours company fundraiser, is something someone wouldn't want on record. That doesn't mean you should say it in-person in the break room where you're not on record instead of emailing it. It means you shouldn't use performance reviews as a weapon to coerce things you can't or won't contractually demand from employees.
Two tools are great for combating this sort of malfeasance:
First, slip an acknowledgement for the verbal request in an email. Something like "Hey, the company event Friday night which you mentioned was critical to my performance review. Is that business casual?" or "You told me to get this internal request for your project done before taking care of my urgent customer tickets, here it is." can help you keep a paper trail with implicit acknowledgement.
Second, as long as you're not in California, Delaware, Florida, Illinois, Maryland, Massachusetts, Montana, Nevada, New Hampshire, Pennsylvania, or Washington, and you have an Android, install a call recorder app: https://play.google.com/store/apps/details?id=com.callrecord... was an app I used for a while in a sensitive situation. Even if you never use it, it's nice to have if something was to blow up.
“You know what the E in email stands for? Evidence.”
Not that it really matters. His predecessors have all had plenty of evidence of corruption, have never been as productive as him and they still kept their jobs, so he probably just didn’t want to deal with checking his inbox.
The media doesn't work for us. It works for its shareholders and most media shareholders are pretty alright with corruption in government because they're part of it.
And that's not even taking into account that we'd likely require a trail for accounting to know exactly where money went, so that it can't simply be "cash spent" to give back $50 untraceable to a bunch of people.
Why don't you think that would work?
