Daily quote of the de jour:

Don't shoot the messenger.

Well, I mean it depends on the message. 'Cos like if it happens to be, 'hi I just robbed a convenience store and now I'm going to take your car' or 'the person holding this message is an interplanetary alien and a danger to all life as we know it, but he can't read so shoot him.'
Then I suppose your best course of action IS to shoot the messenger.

Use your own best judgement.
