If you haven't done anything wrong...
There's a general attitude if you haven't done anything wrong, why would you mind. Unfortunately, "done anything wrong" has a rather wide meaning, as any police officer or anyone who reads police blogs will know. In today's Britain, as soon as your ex, neighbour, enemy or total stranger points at you and says you have committed a crime, you have. This is because, thanks to NCRS, as soon as your name is given by the victim, you are recorded as a "suspect" by most police forces. If you are not then arrested, you become an "unactioned suspect", which is seen by Senior Management as the greatest sin since Eve thought "what's the worst that can happen...?" This is because it is a missed opportunity to improve the force's detection rate, or, as my Area Commander puts it, "Provide a top quality service to a traumatised victim of crime."
A supreme amount of pressure is brought to bear on PCs to arrest their "unactioned suspects". I have actually been to a disciplinary interview over my refusal to do so on one occasion. Most officers, myself included, don't want to fight these battles on a day-to-day basis, and just do as they are told.
Of course, as soon as you are arrested, you enter the dream machine that is custody, the criminal justice system, Crown Prosecution Service advice, etc. Your fingerprints and DNA are taken and held forever on the national database. Your photograph is recorded, you are given a Criminal Records Bureau number. "Bad character" evidence is created in that you were once accused of this crime, and the police must have thought there was enough evidence to nick you for it. This can be used against you in a future prosecution.
It is the introduction of these policies and rules that has led to the total abuse of legislation such as the Protection from Harassment Act 1997. Introduced to protect victims from the twisted and murderous stalkers of the world, it is now used to prevent Kyle texting Sally that shes a stpd btch. Harassments are recorded at a rate of 5-10 a day in Blandshire Constabulary, and most will result in someone being arrested for something pathetic.
Applying this to the new glorious database of all phone-calls and emails, while initially it will be used to investigate the most serious of organised crime, terrorism, blackmail, murder, rape, etc, over time it will be used in the trivial inter-domestic/neighbour disputes that the police deal with all the time. Essentially, we will get to the stage where someone can point at you in the street and say "that person's been harassing me", and the police will be able to pull your email, phone and text records.
Apart from the frightening invasion of your privacy, this will all take weeks or months of police work, and will be a supreme and utter waste of everyone's time.
