Citizens with meth labs in their kitchen might have a problem.

Perhaps. It's not really relevant to your broad claim however.

This also illustrates conventional thinking (or lack of ability to learn). Why do dangerous no-knock raids, which are constitutionally very dubious and should be reserved for the real "Al-Quaida is about to pop a nuke" scenarios, when you can arrest the people working the meth lab outside the house and take down the lab at your leisure. Yes, some labs that might have been taken down will not be, but it isn't as if the Drug Warriors lack targets. Are the results of no-knock raids worth the tragic mistakes?
