What should be introduced is a new machine that could sniff out liquad explosives are somethis like that, a sniffer dog wouldn't be a half bad idea either but in the long term the machine would save money.
But the terrorists were very well planned if the Police weren't following this group either today are tomorrow there could have been a mass terror attack apparently a tape was found in one of the houses of a terrorist, I heard someone say on sky news that this had the prospect to be bigger then 9/11 and I can still remember that day as it casts a dark shadow in my mind I can still remember watching the news and then a planecrashing into the second tower.
