Yes and no. If the Police have a search warrant or your consent, they may search you. If they have neither and you're not under arrest, then no. This would be a 4th amendment violation and any evidence obtained through the illegal search would be suppressed. They may only search you incident to arrest, which means after they've verbally informed you that you're under arrest.
police have the rights to seize evidence if its in full view but not if its in someones property otherwise u have to get a warrant
No.
In order to search through someone's home, police officers must aqquire a search warrant, which is just a slip or piece of paper signed by a judge that gives them legal rights to go searching through a person's home. They also must have some sort of evidence on why they are to search someone's home, such as drugs, leads, etc.
It may depend on the circumstances but as a GENERAL RULE they may seize evidence or contraband that is in plain view.
Don't understand the question. How can a warrant "expire before it starts?"
It could be one. There are search warrants and arrest warrants. If you have a search warrant, the police are entitled to search your property. After executing the search warrant, if the police establish probable cause to believe that you committed a crime, they can arrest you. If you have an arrest warrant, it is only a matter of time before the police find you and execute the arrest warrant.
Probable cause
Not unless they have a valid reason, like if they can see something suspicious without searching the house yet.
No
No. They prefer to surprise you. - A.
Its C. The police get warrant before arresting a suspect
Police can use reasonable force to enter a property with a warrant. However, unless it's a no-knock warrant the police will generally give you approximately 15 seconds to come to the door before they force entry.
What they should do is contact the police, either directly or through a lawyer and work it out.
