The trouble with politicians is........
They are far more willing to listen to a real victim, or a tabloid editor, than to the rest of us. Can you imagine the headlines generated when it transpires that a serial rapist or child molester gets away with it for years because his DNA keeps getting erased, each time he is arrested for similar offences, but cleared, or not prosecuted for insufficient evidence.
You and I might say, so it goes, but, any Home Secretary, regardless of political colour, knows that it's easier to stand up to liberals, than political adversaries and tabloid editors when a child or sex crime goes unpunished. Sadly all our politicians are moral cowards these days, and prefer quick cheap and popular, over due process and right. Sorry, but there it is, if you want it changed, become a politician, oh wait, you won't succeed as your views are considered unpopular, even if they are right.
No matter what you think of the current incumbent of the Home Office, it could have been far worse, and by the way, its possible that most of these things weren't her idea in the first place. It takes a long time to get some of these things through, so for most policies you need to look who was pushing for it five years ago.
