For people who have different ideas of what's good practice in normal life, maybe a helpful exercise is to imagine that example in a business context:
"Bob, uh, did you say you doctored a document from a regulated financial institution? And passed it off in a representation in a business transaction? It was inter-state commerce? And you think the transaction might get disputed, and be investigated? ... OK, I think we need to go talk with Legal right now."
Of course, just because something is bad in the conventions of business, doesn't mean it should be considered bad outside of business. But thinking about why it's considered bad in one set of conventions could be helpful.
