I'm assuming you mean 'their analysis,' and no, I don't believe it's possible to have neutral analysis.
It depends. On the generality, the policy should be the responsibility of elected representatives. However, there should be safeguards guaranteeing a minimum level of human rights which the politicians can't interfere with, and individual cases shouldn't be decided by the lynch-mob.
I'm not sure what you're talking about here, but I'm 100% sure that I don't want a large body of ignorant Daily Mail-readers sitting in judgement on people whose cases they know nothing about.
