Interesting topic this.....
I would like to throw in my tuppence worth...
Firstly, any person arrested has an absolute right to legal advice at any time and are told so as soon as they come through the door. That can be on the telephone or in person. As a result, persons who are arrested - if unsure or 'confused' can avail themselves of the services of a solicitor.
Secondly, simple cautions (there are also conditional cautions which came into being as a result of The Criminal Justice Act 2003) have to follow Home Office Guidelines and cannot be offered in every case. In any event, if the offence is suitable, the offer of a simple caution has to be based on key factors:
The evidence must be the same as would support a potentially successful prosecution
The person must ADMIT the offence (and that admission must be clear and reliable)
The person must understand what a caution means and consent to being so cautioned
In practice, a caution is normally administered by a senior officer (Inspector) who should explain the caution process and what it means after satisfying themselves of the evidential threshold and that there is a clear and reliable admission.
Finally, the caution form itself has a clear explanation of what the person is signing for.
All these safeguards are in place to ensure that the person fully understands the process before signing to accept the caution.
A simple caution is an alternative to prosecution. It is not a 'cop out' (no pun intended) by the police or CPS. If the guidance is adhered to then the person is offered a viable alternative to what may well be a subsequent conviction at court (and all that entails)
Whether the person is cautioned or charged, the police still get their 'figures' ( the offence is deemed to have been detected) even if the person is subsequently found Not Guilty at court. Therefore, it matters not to the police whether a person accepts a caution or is charged to go before the court.
There are additional benefits to the person in not having to go through the whole court process and avoding a possible conviction which may have to be disclosed subsequently.
Furthermore, unlike what had gone before, The Rehabilitation Of Offenders Act 1974 was amended as of 10th March this year (2014) by The Legal Aid, Sentencing and Punishment of Offenders Act 2012 making simple caution spent IMMEDIATELY.
The result is that, apart from some specified professions/jobs and certain categories of offence, there is now no requirement to declare a simple caution when applying for a job.
I appreciate that there are many 'horror stories' going about in respect of innocent people accepting cautions but I take these with a pinch of salt..
