101,248 people were stopped and searched last year in England, Wales and Scotland under Section 44 of the Terrorism Act.
506 of those searches resulted in arrests. None of those arrests were for terrorist offences. I suspect many were for objecting to being stopped
Since July, the police are not allowed to stop and search people unless they "reasonably suspect" them of being a terrorist. It will be interesting to hear what those "reasons" have been so far.
