According to journalists’ firsthand accounts found in the live streaming video from Tim Pool of Vice News (posted above, but may not be currently live), police or National Guard troops are now sweeping houses door to door in Ferguson, MO. Thumbnail credit: Ryan J. Reilly

This is a blatant violation of the constitution under the 4th amendment:

“The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.”
