No, the murder in its self authorizes a search by virtue of the severity of the crime. It becomes a crime scene and is subject to the collection of evidence with out the need of a warrant.
If the police have probable cause to believe that a crime is being committed, they can search a house without a warrant. There are too many variables for a short answer. The short answer is you can tell the police they are not allowed to search your house. Be sure you record it if you can, but DO NOT resist. If they continue to search the house you can pursue legal remedies such as a law suit or, trying to have evidence thrown out should the police uncover something due to an illegal search.
yes
The police got a search warrent in order to search the suspect's house. The suspect would not allow the police to search his home without a search warrant.
The police can search a house on suspicion of the presence of drugs is a couple conditions are met. Firstly, if they have gone before a judge and been granted a warrant, then the house can be searched in accordance with the warrant. Second, if the police can demonstrate probable cause to suspect that there is illegal activity occurring in the house (i.e. the possession of drugs) then it can be searched but that search can be challenged on 4th Amendment grounds.
Police can search a private home if they have a warrant to search a house. There may be some exceptions under the Patriot Act.
I guess that they search you first. If something weird is in your house then on your body might help to see what you're up to!
Sure.
Who ever owns the house and pays the bills should make the desision.
yes they have to have a paper signed by a judge
I'll give an example. When police come knocking at your door, demanding you to open up and let them search the house, you can say, "No, I need to see your search warrant." The police MUST have a search warrant in order to search your house and if they don't, you can kick them out! :) Hehe.
Absolutely... The search warrant gives the authority for the police to search any part of the address for which it was granted. It also grants permission to search the grounds surrounding the house up to the boundary fences - including any outbuildings within the boundary. Additionally - it also gives the police permission to search any person found in the property OR any person who visits the property while the search is being carried out !
