Yes, I was saying the same thing absent Low level offending like shop theft is a very different matter from sexual offences that are viewed by the police as low level. The thinking and intention of the offender can be sinister. Practising for putting fantasies into action, networking for future conact with paedophiles, creating 'accidental' exposure incidents which become a ten times a day habit - police can't be aware of intentions if they are happy to accept an offender saying 'yeah, sorry, didn't mean it, won't do it again). In-depth assessments are needed for that.
The one thing I would say in favour of SOME of these cautions is that the police do obtain and record an admission of guilt in order to caution. If a solicitor comes along and convinces them that they haven't got a cat in hell's chance of getting a guilty verdict, the offender won't plead guilty if they try it (but they will accept a caution), if taken to court remand in custody will be opposed, or a period of remand will mean a walk-out if the guilty verdict results in a few weeks custody, on balance the caution will be implemented immediately and any further suspicions will be acted on, searches and seizures of potental evidence will easier to carry out, and an existing guilty admission will undermine further attempts to avoid prosecution.
