Policing the Internet

The topic of whether the Internet should be policed sparks heated debates amongst many users. They are however many pros and cons to this argument.

Pros – Inappropriate content can be removed from the Internet by censoring adult websites.

Cons – It is very difficult to police the whole Internet society as it is very big and it also affects the freedom of speech argument.

My personal opinion on the matter would be that in a perfect world you would be able to police the Internet but it is not realistically possible.

The Internet and the Law

Copyright, Designs and Patents Act – Ensures that websites cannot use other people’s work without their authorisation.

Computer Misuse Act – Ensures that computers are not used in a malicious manner to harm other people or organisations.

Data Protection Act – Ensures that the data that is held about the data subject is not misused by the data user.
