A crime scene where no crime occurred!

I'm sorry but something MAgunowner said reminded me of this from Monty Python (Which I have augmented):

One glance confirmed his suspicions. Behind a bush, on the side of the road, there was no severed arm. No dismembered trunk of a man in his late fifties. No dead, decmoposing, nude body of a teenage prostitute. No signs of any illicit substances. No head in a bag. No illegal gambling operation. No child pornography. Nothing. Not a sausage. The area was absolutely devoid of any criminal activity. For Detective Sergeant Jones, this was not to be the start of any trail of events which would not, in no time at all, involve him in neither a tangled knot of suspicion, nor any web of lies, which would, had he been not involved, surely have led him to no other place, than the central criminal court of the Old Bailey.

Worse, there was no gun to be found! Nothing that looked like a firearm was anywhere in the vicinity!
