And you again failed to step to the plate and deliver what you claim you can. Instead you merely engage in attack.
Since we have no nation wide system of registration for firearms, how does anyone know if it is useful or not?
In Canada In a Canada Firearms Centre (CAFC) survey, 74% of general duty police officers stated that the registry "query results have proven beneficial during major operations." That pretty much destroys your claim that police have no use for registration.
And you say you "demonstrated" this but where is it?
Where is your factual refutation of what I presented yesterday in 327? You rejected the findings for the very reason that I said you reject all firearms information like this and it proves the intellectual fraud in asking for the data in the first place.
