Your question is daft. My answer, if it wasn't clear, is that 2 entirely different cases, on different facts, cannot be compared.
If you think Brand's sentence was too tough or lenient, that's your prerogative. What you think though isn't clear.
If you think another, wholly unrelated offence, was too tough or lenient, that's your prerogative. If it's light, it has nothing whatsoever to do with the Brand sentence (which was too light - it was anal rape ffs).
The judiciary isn't politically influenced. That's nonsense. I'm not sure how you arrive at that conclusion, or think it works. Do you believe that politicians send emails to judges, or appear at the judicial college, to tell judges (who's oath is to work without fear or favour) what to do to keep the government of the day sweet?
I'm intrigued - how does this political influence work?
