Yes ~M~ I was 'guest' who forgot to fill the form in!
I really don't know and it is a problem that needs considerable thought. But the problem remains that jurors will not convict a police officer and are impressed by (so called) expert witnesses. I believe the latter is being looked into.
I suppose voting is similar; perhaps newsagents should report to some committee which newspapers we buy! Not so funny - we are 'registered' when we buy a television. Seriously how can we call ourselves a democracy when the government is chosen by the floating voters in the marginals; apart from having hereditary peers and a number of bishops in the House of Lords. The government refused to do anything about the former and constantly drag their heels about the latter.
