Terrorism Bill

The Home Secretary is rightly dealing with the theme of values. What about the value to which Lord Carlile referred when he criticised the excessive use of section 44 of the Terrorism Act 2000? He described its use as a substantial encroachment into the reasonable expectation of the public at large that they would face police intervention in their lives only if there was a reasonable suspicion that they would commit a crime. Is not that value threatened if events such as those at the Labour party conference or the instance of the person who was told that she could not walk on a cycle path occur?
