Hi Michael
I'm not an expert on this, and your question is outside the scope of the forum. I did look up criminal injury payments, and as far as I can work out, you have a 52-week buffer with regard to it affecting means-tested benefits (which is what the CA told you) - but I can't find it on the government website to confirm.
