I read a story somewhere about a couple who encountered someone (or two people) running in slightly odd circumstances, and joked, if these were robbers running away from the crime, would we be able to describe them? Just for entertainment, they wrote down as exact a description of the people as they could.
Turned out that's exactly what had happened, and the meticulous, deliberate descriptions led the cops to the right people in very short order. I think that sort of occurrence must be pretty rare though.
For another identification horror show, see here. www.vetpath.co.uk/lockerbie/photoid.pdf

Pfft typical you - trying to derail the thread again with your Lockerbie schtick
But yes, I'd say that such occurrences were vanishingly rare.
In addition to the two extremes of 1) pre-warning of a crime (as per the bank alarm alerting a passer-by to look out for what's happening) and 2) nothing at all out of the ordinary (the situation around Piazza Grimana on the night of the murder), there's also a middle third ground. That's the one where the witness is surprised by witnessing the commission of the crime, and where the whole event is over quickly. This is the scenario that's often used in experiments, some of which were described by others above. A group of unsuspecting people are exposed to a sudden snatch-and-grab robbery, and are then invited to recount what happened (how many assailants, what happened, identification of assailants...)
As others have noted, these sorts of experiments consistently show that people - especially when they are unprepared for the need to remember identification (and other crime-related) details - can get things significantly wrong in their recollections. And if that's the case, it's even more likely that people will falter in their recollections of events that were of no seeming significance at the time.
And that's before we even get on to the effects of long-term heroin abuse on memory and judgement. Oh, and before we even get onto the list of compelling reasons why a homeless drug addict might want to "help" the authorities in order to curry some favour with them, especially when he has "previous" in this regard........
