Policing and Crime Bill

I just raise one question on these amendments, although I readily accept that, perhaps if I had read everything sent to me, I would not be asking such questions. As the Minister said, this talks about an extension of powers to immigration officers, Revenue and Customs officers, the British Transport Police and others. Should these provisions have been included earlier in the Bill and it has just been realised that they were not there, hence these amendments being brought forward, or is this some completely new power? If so, what has been happening up to now? What have been the consequences of not having these powers? How detrimental has that been?
