Let's assume you meant "can't simply extrapolate" but, unfortunately, you can’t assume anything with some of the posters on here. Small sample time? Ignored facets? Do you really think anyone is going to create and present some sort of academic paper on murder rates just to make a point on football messageboard? You are clutching at straws. My aim was to show how looking at the lifetime chance of being murdered rather than the yearly average gives you a different impression of the murder rate. I am sure you will be the first to congratulate me on achieving that objective. If the murder rate in Cardiff is 1.7 per 100,000 then that seems much safer than saying you have a 1 in 735 chance of being murdered before you are 80 even though, given many obvious assumptions, they mean the same thing.
