I believe they do need a warrant to check private property but if the safe is in the car and your entering a restricted area then they wont be needing a warrant.
ADDED: The questioner has neatly left out any explanation as to how and why this safe had anything to do with their vehicle. The police would have been derelict in their duty if they had not looked into the circumstances that they were apparently faced with. If the police had reasonable suspicion that this "un-attached" safe might be the "fruits of a crime" they will take action to either confirm their suspicion or set their suspicion to rest. After all . . . how many people drive around with "un-attached" safes in, or on, their car?
If they have a warrant.
yes police can do what they want including kill you
If the garage is attached to the home, yes they can search the entire premises.
If the basement is attached to the structure it is considered to be part of the structure, and no separate search warrant is needed.
No, but you can turn yourself in and pay the bail. Exception: if the warrant is for failure to appear on a traffic offense, you can generally pay off the fines and the warrant will be recalled.
no
Yes. The police can search any items if they have a warrant. It does not matter that no one is there to receive the warrant. The police only have to leave a copy of the warrant at the residence.
The whole point of having a police officer directing traffic is that he will override the traffic signals in order to create a better flow of traffic. This can be necessary during unusual happenings such as a traffic accident or a sports stadium emptying out. If motorists were going to obey the traffic lights anyway, there would be no point in putting the police officer there!
No they can't. If they try to use it in court it would be immiscible.
Police can question anyone if they have the proper authority (e.g. warrant), but parent or guardian is authorized to be present during questioning of a child.
No. The service of a warrant when the officers are notified by telephone or radio has been repeatedly upheld. The burden on law enforcement of requiring them to present a physical warrant would be unreasonable, most particularly when a very large percentage of warrants are served during unexpected encounters between police and the subject of the warrant.
A warrant is a warrant. If you happen to be one those who gets randomly screened and your name is run through the criminal information computer AND the warrants are on file you COULD be taken into custody by the airport police.
