You have my sympathy John. I don't know exactly what the answer is, but we can forget all about a simple quick fix answer to terrorism. A lot of the eye catching, dramatic responses are only for the politicians' own audiences and will have little effect on a complex and persitent problem. In the long term it will mean engaging with the causes and breeding grounds of terrorism. It has long been my belief that the refugee camps of displaced people in the Middle East have produced more terrorists than all the political tracts in the world. The measures you are talking about have been designed only to play to the gallery. The terrorists aren't in the gallery.
