They can't so if one did he could be fired
In the US, such authority for government officials does not exist.
The two basic types of arrest are "arrest with a warrant" and "arrest without a warrant." An arrest with a warrant occurs when law enforcement obtains a legal document from a judge authorizing the arrest of an individual based on probable cause. In contrast, an arrest without a warrant can happen when an officer has probable cause to believe that a person has committed a crime, allowing for immediate action without prior judicial approval.
Unless you're an law enforcement officer, you can't obtain a standard Search Warrant (if you are, your Sergeant can help with this). You have the chance to obtain an Ex Partite warrant, but it's unlikley without at least the tacit cooperation of law enforcement. An affadavit won't help as you can't execute due process without being an officer of the law or a duly deputized agent.
An officer of the law can only search for evidence if they have reasonable cause in doing so. All persons do however have the right to see a warrant before allowing a search, which is their right. All officers are aware of this, however, and if asked will produce a warrant. Without this warrant the evidence may be inadmissible in the court of law.Law Enforcement does not have to show you the warrantprior to serving it, or arresting you. Simply the knowledge that the warrant exists is sufficient for them to conduct their activity.They must, however, leave a copy of a search warrant at the residence, if it was a search warrant for a home, and an inventory of things taken, if any.
Try calling your local law enforcement on the phone agency and asking. Some times they will give the information, some won't.
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.
NO. He can search your car if he has just cause without a warrant.
noAnother View:If the officer(s) had entered (or was ALLOWED to enter) your residence in a lawful manner, then they could take a picture of anything, they could see with their own eyes from their vantage point.However, without a warrant, they are not legally allowed to conduct a walk-through of your entire residence snapping pictures as they go.Unless they are there to conduct a law enforcement function you can 'invite' them to leave at any time you wish.
Unreasonable searches are those performed without a warrant or probable cause. Probable cause is established when a law enforcement officer can reasonably suspect the commission of a crime, without explicitly violating the suspect's expectation of privacy. For instance, if someone were to rob another person on the street in plain view of others, and then run into his private home, an officer could enter the property and apprehend the criminal. But if an officer randomly decided to search a house without permission or a search warrant, the search would be unreasonable, and the fruits of the search would be suppressed in court.
Only where probably cause exists.
no no
Yes, a police officer can legally approach a parked car without a warrant or probable cause as long as they are conducting a routine patrol or have reasonable suspicion of criminal activity.
