The costs of policing are ever escalating and in most cases, whether solved or not, murder investigations cost millions.
In the circumstances, would it not seem sensible, seven days after the event, to offer a reward of £500.000 for information leading to a conviction. This could be much more effective and cost-efficlent than plodding on with the investigation.
If you know someone who would be interested in this proposal, please pass it on.
