How do you react when you see a tall story here that you know not to be true? Do you call it out or let it slide if you can see no harm?

I’ve seen one or two posts here that sometimes talk about areas like the military that because of my experience I know they are spinning a yarn, but they aren’t claiming to achieved something others actually did or anything deceitful like that I have tended to turn a blind eye. Some people here are engineers or work in legal circles who might have experienced something similar.

So do you let it pass or ring the bell and get involved?
