There are organizational methods they cannot defeat.
First, and most importantly, small cells composed of folks who are either family or close friends from childhood.
NEVER discuss operation plans except in a private home, which requires a Warrant to listen to.
Never join large militia, though it's OK and desirable to show up unannounced when others need help.
When the boy’z in black roll in, it's for keeps.
I agree that words of caution is needed when discussion militia planning; however the legal requirement of needing a warrant before invading a private home is a joke.
We’ve seen too many examples of police home invasions and monitoring a private(?) conversation to think that whatever the police state wants to do, it will do it.
