The first law we don’t need is what is considered to be an absolute right.
The right to life -
what it actually means is that every single one of us has an absolute right to life - no ifs ands or buts. Who is it protecting us from? Well, authoritarian people like Putin or Xi who can with impunity kill people like political opponents or someone simply because they have the temerity to criticise their actions. Or look at South America and the murders, carried out there by the governments whim. No ECHR protection for those people - who needs it anyway?
So what this law does in practice is protect the population from governments who as we saw in the 1930s, and as we are seeing in many areas of the world now, will commit horrendous acts of violence/murder against minorities in particular and individuals at a whim.
Governments are not benign they always have a tendency to use the law to its maximum or indeed operate outside of the law, unless they are kept in check by agreed rules such as the EHCR.
That was the lesson learned by our parents and trying to be undermined by Farage.
