Copyright law differs from jurisdiction to jurisdiction.
Not all reproductions of copyright works are restricted by copyright.
In the US for example there is a general "fair use" exemption - which the UK does not have.
In the US there is a general "private use" exemption - which the UK does not have.
The duration of copyright in the USA in a number of cases differs from the UK.
The US law on devolution of copyright differs substantially from the UK.
The US law on copyright (or similar rights) in physical models differs considerably from the UK - see the "Star Wars" case.
Even where there is an infringment of copyright, it may be easy to see where the reproduction took place, but it may be very hard to see what amounts to "authorisation" and if there was "authorisation" where it took place.

Bert, you really need to learn something about the law of copyright (and even criminal law) before pontificating.
