Yes. They need a warrant unless you give them permission to enter. It does not matter if you know the person or not, they either need a warrant or your permission to enter your house to search for anything including a person.
Because the authorities strongly suspect that the 'something' or 'someone' they are looking for is more likely to be there after dark.
I heard that you can ask the police to do a free warrant search on you at any time. Can you ask them to do a free warrant search on someone else?
Yes, you can search if someone has a warrant by contacting the local police department or checking online databases maintained by law enforcement agencies.
It depends on who they are, who you are, if they have a warrant or reason to search, and what you are trying to do.
No problem. It's lawful. That's why they left a copy of the warrant. There is no requirement that someone be there when the premises is being searched. The authorities were obviously looking for WHAT was in the home and not WHO was in the home.
If they were arrested as a result of a search warrant being executed - it all depends on what the search warrant was for (what crime/offense) and whether the evidence being searched for was found (I'm assuming it was).
Yes. Enforcement officers do not need a search warrant in a variety of instances. If there is consent to a search, you do not need a warrant. If something is in plain view, you do not need a warrant. Also, warrants are not needed in emergency situations when the public safety is in danger.
When someone doesn't answer the phone when government comes to search the home with a search warrant.
What the object of the search warrant is, IE, if you're looking for a firearm, or ilegal narcotics, or a candlestick in the library.
No.
To obtain a search warrant an officer must go before a judge and explain the reason for the search. The warrant will list the reason or reasons why they are searching, what they are looking for, and why. please refer to this link for more information, http://en.wikipedia.org/wiki/Search_warrant
