First, there's nothing necessarily "sophisticated " about pressure cooker bombs. A pressure cooker, some explosives, some ball bearings and nails for shrapnel, an ignition device.
Until we know more about the bombs' configuration, we can't conclude they were "sophisticated".
Second, if this was a sophisticated plan, with full sleeper cell support, why did these guys end up without cash and transportation when they discovered they'd been IDed by surveillance cameras?
Why no disguises or deception to foil the surveillance cameras? Why, instead,m the distinctive white cap, worn backward?
There were some very amateurish aspects to the plan and its execution.
low-level expendables,like the kids and women they got to strap on bombs in Iraq. somebody is showing our intelligence services how easy it is.
I concur.
Robbing greedy marts, running from the cops, jumping fences and hiding in backyard boats?
These guys sound more like your typical American hating foreigners, who the government has imported by the millions, legally and illegally.
