The article does not say there was an immitation firearm used. Rather, that since they did not recover the shotgun it is easier to prove an immitation firearms offence so that's the charges. No effect or relevance to airsoft there. Other than that it is easier for police to prosecute replica charges than real steel charges. Why take actual dangerous items off the street when you can cut down on the number of toys, neh? d:
Offense cannot be given, only taken.
