How is the defence against terrorism?

Look at how terrorists can breach the intelligence of Russia n commmit a massacre during a concert? How well prepared is our defences as the piracy attacks on Lahad Datu in Sabah shows the authorities underestimate the abilities of terrorist to attack the public It might range from sophisticated weapons to even ramming a vehicle into crowds.it could range from releasing toxic gases in subways like how the authorities in Singapore educates public to be alert to suspicious luggage left unattended in public areas to extra precaution at hotels n concert venues yes a few gunshots were fired in kl international airport terminal 1 and a person seriously injured and it was a personal feud but they miss the point.how the heck can public security be so lax that a man can enter the arrival hall with his gun undetected.An intelligent urban terrorist would be smart enough to do reconnaisance groundwork to pinpoint the breach in security in our international airport .so scary as any place of mass public traffic is susceptible as Bangkok lapse has demonstrated lax security. How is it possible for an israel agent able to buy guns from a Malaysian middleman? Didnt a citizen of North Korea get assasinated at the KLIA airport some years ago.where are security scanners at entrance n exit of KLIA or sniffer dogs on patrol for drugs or bombs congrats police for nabbing suspect with gun.its good as public feel safer without risk of mass killing as in the australian mall where 6 bystangers were killed by a mentally sick man.good also cops didnt fire in enclosed KLIA or more bystanders may be injured.nowadays where lives of innocent people are at risk,public security comes first. < b>
