Hoping it is all over soon, with no injuries.
I don't understand why target the coffee shop, if he felt the need to target any one, which he obviously did, why not target the TV studio across the road, that way he can use the media get across what ever the point to all this is, without the need to take hostages.
Basically hold the channel 7 network to ransom, to get his message across - he must have one, what ever it must be...I mean a coffee shop???
