Opaque walls in private homes enable the residents of those home to commit crimes. The detection and prosecution of those crimes is a difficult task due to the use of opaque walls. All building contractors need to take responsibility, and join together to reduce and eliminate those crimes. I propose that it should not be permitted to build any new private homes whose walls are made from opaque materials.
Have you noticed the difference between my proposal and the BBC's proposal? That's right - the crimes enabled by opaque walls do not threaten to reduce the profits of large media corporations like the BBC. Ah well, I guess my proposal doesn't have much chance of adoption, then.
