Yes, if the LEO observes you in the commission of a crime and/or has probable cause. Warrants are generally only required for crimes not observed by law enforcement, but after sufficient evidence (or probable cause) has been obtained through investigative or forensic work.
Added: Also - if you are 'wanted' on a warrant and the LEO sees and identifies you as the wanted subject, they do NOT need the warrant in their possession to 'serve' it and arrest you on the spot. Their mere knowledge of its existence is sufficient.
Yes, a search warrant is only required to examine the property of someone who has not been arrested.
Yes they can search it
Yes.
A search warrant is NOT necessarily an arrest warrant. If some other violation comes to light during the search that supports your arrest, yes, you could be arrested, even if nothing was found during the search.
When he has a warrant, when you get arrested and if you give them permission to search you
You can be arrested and detained without a warrant. A criminal attorney can give you some help, and if you have been arrested, you should consult one immediately.
An arrest warrant must name or specifically describe the person(s) to be arrested.
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.
When the person named in the warrant is arrested, he will be held without bail.
Yes i you have a warrant, but not technically.
A warrant is an order for an arrest issued by the court. But many arrests do not need a warrant. If you punch someone in the face, and police are called, you will be arrested without a warrant, and one will not be needed. If say, you failed to show up in court, then a warrant for your arrest will be issued, to alert all officers that you should be arrested on sight. So the warrant itself is not the thing 'allowing' you to be arrested.
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.
