"And exactly when did the Branch Davidians call for the forcible overthrow of the government?"
It doesn't matter; when you give the government ANY power, it will be abused to some degree, generally proportionate to the amount of power. That is why conservatives oppose granting large amounts of power to the government. Giving the government the power to outlaw an entire religion is giving the government a lot of power--so, one can expect that it will be abused on a truly massive scale.
"If the laws had been enforced as intended, Waco would never have made national news."
In other words, if everything was perfect, and nobody had a speck of evil in their hearts, Waco would never have made national news.
Bad news for you: nothing is perfect and who knows what evil lurks in the hearts of men? (Well, besides God and The Shadow, of course.)
Nope, you've got my argument all wrong. As far as the laws go, it is likely that everything at Waco was legal. There were questions about guns & child abuse, but I heard only allegations, and never saw anything suggesting there were facts behind the allegations. The government should have treated them as if they had hearts of gold, until PROVEN otherwise. I'm questioning your moral relativism in equating the protection of the innocent at Waco, with the protection of the mullahs. 9/11 is a lot of proof in the case of the mullahs.
If we can't get the the government to make such simple distinctions, we might as well submit to the Caliphate.
