I think Control Orders should be scrapped in their current form. It is just wrong to enable some people (police or customs and excise for example) to arrest others without saying why!!. It is a "Sus" law really: based on suspicion but you are not told what it is you are supposed to be suspected of!
SCRAP Contol Order Law.
Why does this idea matter?
I know you would be furious if you were arrested and held without having any way of finding out WHY! So don't be surprised if you are taken in under the law of Control Orders, and held without being told why!!
