Even if we identify a potential terrorist, we have no powers to hold them because it would infringe their human rights (this was decided in the courts by a judge).
So we put them on a control order where they stay free and we trust them to report to the police every so often.
But 7 of these people on control order have disappeared and the police and security people have no idea where they are. see here:

Strange that when the second world war started EVERY German in this country was put in a prison camp or fenced in area, even if we had no evidence against them.
Nowadays we identify a potential terrorist and cant even lock them up but have to allow them to walk free.
How about we lock EVERY muslim up in a prison camp. Those that dont like it can leave the country.
Wouldn't that be wonderful, we could have our country back.
