In the United States, we are protected by the Constitution from such searches. Police may only search if: 1) they ask and get permission, or 2) they have a warrant. A warrant must be issued by a judge who makes the decision on whether or not there is sufficient evidence to indicate a likely crime.
Most drugs are not illegal. Most houses are full of all sorts of drugs. You are probably referring to contraband drugs.
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.
Who ever owns the house and pays the bills should make the desision.
If they ask your permission and you grant it, absolutely.
if they find illegal drugs or a unregistered gun in your car they can have permission to enter your home for the reason they have met you for
It is possible that if the police were there at the time the drugs were sold then an exigent circumstance exception could apply. However that is not normally the case. Most often the information about drug sales are presented to a magistrate and a warrant is obtained. The police may then do a controlled buy to confirm drugs are in the house immediately prior to the warrant service.
The police broke into the house to search for evidence related to a crime or to apprehend a suspect.
arrested yes convicted no.
First, you cannot obtain a search warrant. Police and prosecutors can, but only if they have enough evidence that there has been a crime, and that searching might solve it. Search warrants must be issued by judges.
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.
