Perhaps it would be better in such a subject to forgo sarcasm, to say what one means as carefully as possible and mean what one says.

Regarding guns: if guns are illegal only criminals will have guns. Hitler outlawed guns... Countries with the most stringent gun laws do NOT, statistically, have the least murders. Guns/weapons are not the problem. People are. Attitudes are. Mind your own and pass it on.

Re the CIA/FBI issue: it is known that CIA knew the attacks were being planned on the WTC. They knew the culprits and were watching them, and allowed them to move in and out of the U.S. at will. The info was not shared. Who are the criminals? I do not doubt for one moment that one or both of these were involved in those assassinations, as Bobert suggests, regardless of who was blamed publicly.
