I recently got in trouble with the law. How can I find out if I have a warrant for my arrest without contacting the authorities?
Yes, the officer may search. Police may search a building if they reasonably believe a valid search warrant has been issued. They do not have to possess the search warrant.
I am not familiar with all California law but I would say the answer to this question is yes. A police officer can answer your cell phone, but, they may not search (look at contacts etc.) without a warrant.
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.
Depends on what you mean by "bugged", wiretapped or harassed. The answer is no to wiretapping without a warrant and no the police cannot legally harass you.
Take your ID and go in to the local police department.
