The Police are looking for the terrorists. Could you help me? I'm interested in applying for the job. ...Otherwise, good job :)

The police is looking for the terrorists. John stayed at his mother-in-law's house last night. That was by far the best film I've ever seen.

All correct except "The police is looking for the terrorists." The police are looking for the terrorists (police is a plural noun .It is made up of many people, and each of them is looking for the terrorist)) A policeman is looking for ..... The police force is ......( as a singular group) The police in my country ( talking about policemen here> plural ) are not too bad , but the police force IS control by the government (police force is an organization/A grouping of people >singular)

English isn't my native language, but maybe i can help you. The Police is looking for the terrorists(but i think that using search for is better) John stayed at the hause of his mother-in-law last night. By far that was the best film I've ever seen.
