I guess my main concern here is that despite Bukit Bintang and the Pavilion Shopping mall being specifically named as potential targets, there is no visible security to reassure people that the authorities are doing anything to protect them.
Are the armed police/security guards actually here but maybe just hiding somewhere? It's no good hiding inside; terrorists have to be prevented from entering the shopping mall in the first place. Their targets - large groups of people - are found inside, not outside. With no security at the entrance a suicide bomber could just walk straight in.
And where are the metal detectors? Why isn't anyone checking bags?
I was slightly reassured when I read about the arrest on the monorail. But then, how did he get into the station and onto the train? He could have detonated the device on the train.
