I know we have had discussions on the legalities of these door to door searches already so setting that aside what about the frequency of them occurring. After reading another article on a locked down, SWAT roaming the streets, city it seems this is becoming the go to standard for LEO. For reference there was Christopher Dorner CA, 2/7/13, Dzhokhar Tsarnaev MA, 4/19/13, stabbing suspect CA, 4/19/13 and that's just off the top of my head. Is this the media flavor of the week or is it a change in tactical response?
