The team that made the 1993 World Trade Center attempt were a small group, maybe what, six, eight guys including the Blind Sheikh?
At the time, USG sources were telling media that the towers were in no way ever in danger from Sheikh Abdul's truck bomb. More recently, I saw a statement that if it hadn't been for the prime spot's having been occupied by parked federal agency vehicles, their plan might actually have worked, and dropped Trade 1 with 25,000 people in it in the middle of the afternoon. Doubtful that bringing down Trade 1 would have broken the foundations of Trade 2 and brought it down, too (after all, that didn't happen on 9/11), but if it had, that would have been more than 50,000 dead, including the workers in WTC 4, 5, and 6 and the Marriott Hotel adjacent (and the Marriott hadn't yet been structurally strengthened, which was something done after the bombing).
That's the kind of stuff they were thinking about, not Obama's giant gun-grab wet dream.
If it is necessary to imprison 330 million people, because of six or a dozen terrorists, the terrorists do actually win.
The Bill of Rights exists, not because government granted it, or has any authority to reduce it, no matter how important they think a reason is for reducing it. The US fought in World War II while keeping its liberties, and when Nazi saboteurs landed in Florida, we captured then eventually hung them.
Face it, the FBI exists for domestic security, against enemies, foreign and domestic. You don’t need massive new agencies to do that. You don’t need to monitor all transportation and communications to do that. You do not need a police state to do that.
