The approach was simple. The teams went door to door, knocked with weapons at the ready, perp-walked entire families into the streets (under the view of raised guns,) then entered the homes, unmolested, to conduct their search. The homeowners were all cowed and bleating at curbside like the sheep they are.
If that happens in the next 5 minutes in your neighborhood, with fifteen body-armored, jack boots knocking at the door to confiscate your guns, how many will you take out before they slay you and your family? Watching the slaughter from next door, how many of your neighbors will now answer their doors with shotgun in hand? I do not disparage the courage of those who would answer their doors with the intent to defend their 2nd Amendment right, but I do not see even a martyr's effect on the local or national level. Technology, communications, organization and career maintenance are on the side of the opposition.
Without a better plan, such citizen bravery will not even make page 13 of the local gazette.
