This 1996 incident in Tasmania was used as a pretext to essentially disarm Australia....
The perfect ISIS attack:
A dozen battle hardened and trained, committed Jihadis separately travel to the US via established border routes. Aided, perhaps, by the Mexican gangs that control the border.
Each with $10k cash, fake ID and a predesignated rendezvous.
At least 6 will make it.
They can then purchase good weapons and optics in the US from illegal sources.
Keeping their eyes on the internet they looked for large, planned protests that happen on short notice and again rendezvous, this time with weapons and ammo.
6 trained, experienced men with AR's and adequate ammo could defeat most police forces and may even escape.
A couple of hundred cops with pistols, 1,000 protesters could all be killed.
Cops that survive and get to acquire their carbine will be VERY cautious in pursuit.
New protocol MUST be to surround the cops that are surrounding the protesters with trained, well-armed tactical teams.
That is the lesson of Dallas and I hope everyone is paying attention.
