Murder is one thing, some superior telling you you cannot accept random PDFs sent to you via email for whatever reason and you following that policy is another.

Murder is one thing, some superior telling you you cannot accept random PDFs sent to you via email for whatever reason and you following that policy is another. Imagine you run a cash only cafe and one of your baristas starts accepting payment via paypal as a convenience to your customers. Your customers would totally dig it and see it as the morally right thing to do. You however might see some justified problems with it. If a government office cannot accept pdfs due to policy, the policy is at fault, not the person forced to carry it out. We do not want to live in a world where office clerks make there own rules and ignore policy, based on their subjective morality, with the exception of rejecting or subverting obviously morally wrong extreme policies. Not accepting PDFs is not extreme, it is just bullshit.
