Terrorism Bill

Like many hon. Members, I am oscillating about the clause. Like my hon. Friend the Member for Stroud (Mr. Drew), I have constituents who were detained, stopped and searched and, in many cases, harassed under the Terrorism Act 2000 for protesting peacefully outside Fairford—I have good evidence that they were inappropriately harassed. I am worried that similar circumstances could arise under the Bill. Although I am clear about the boundary and I can understand that someone who crosses the boundary commits an offence, I remain unclear about the reason for including such a provision in the Terrorism Bill. If someone got over a perimeter fence and proved to be a terrorist, surely he could be charged under other legislation rather than simply being charged with crossing the perimeter fence.
