Surely, what you have written is the opposite of what is true?
Just to clarify, what you have written is that:
1. if I fraudulently acquire £50 and I admit this to my solicitor, the solicitor must dob me in.
2. if I have committed a major terrorist act, killing 5 people in the process and admit this to my solicitor, my solicitor is not legally obliged to inform any other authorities about my admission.
Have I got this correct?
No, if you tell the solicitor you are GOING to commit fraud then they must disclose.
If you tell the solicitor you HAVE committed fraud then they don't.
All this is of course in the course of your engagement with the solicitor, not just if it's random chit chat

Essentially a solicitor can't help you commit crime.
