Jesus Christ guys! If you want to be a terrorist:
1) Pay as you go phone £15 - use it for a day then ditch it.
2) Arrange meetings on train / bus stations / Hampstead Heath, anywhere strangers are known to 'sit' next to each other.
3) Dress age appropriately.
4) Any important info to be hand delivered (children make the best couriers if not too far).
5) The law of fives. Fnord!
When governments, pc makers and search engines are spying on every facet of our lives, when the western world condones torture as an acceptable tool, when 21 centuries of existence see's us still stoning women then you know we, as a species, are fucked!
