My property is posted. It is illegal for anyone, including law enforcement officers, to come on to my property without a warrant unless they see or hear something that leads them to believe somones safety is in question. I can use what ever force is necessary to protect my property, my home and myself if anyone should trespass.
What the cops did was an unlawful search, criminal trespass and unlawfull detainment. Anyone of them could have been perceived as an armed threat to a homeowner and shot - lawfully with no criminal charges possible against the home owner. Law enforcement cannot suspend the rights of the individual to suit their desire to catch a crook or a terrorist. Unwarranted house to house searches by the Brittish was the exact reason that the fourth amendment was spelled out to protect the privacy and homes of citizens from searches just like that!
I hope the whole bunch of them sue the city for civil rights violations!
