I think we’ve already published a version of this. Here it is as revised for the Libertarian Alliance:
Over the past twenty-five years fundamental safeguards have been removed or are in danger of being removed from our legal system through measures such as the Serious Crime and Disorder Act, various anti-terrorism laws, the retention of the fingerprints and DNA of those not found guilty of a crime and the breach of the convention that no one is placed in “double jeopardy” by being tried twice for the same offence. At the same time, the whole thrust of government policy and behaviour is ever more authoritarian, vide the neutering of Parliament, the series of gratuitous and aggressive wars and the increasingly intolerant treatment of protestors. In such circumstances the chances of becoming involved with the criminal law are increasing even for the law abiding. That being so it pays to be prepared to deal with the police, lawyers and the courts. This is what the guide is designed to do.
