There are no statutes of limitations on the prosecution of homicide or murder.
You could try a citizen's arrest but the police man may refuse to be arrested. It is only a warranted police officer that is empowered by society to forcibly arrest someone.
Never, because shooting somebody is breaking the law and murder.
Yes, if police have taken someone into custody, they are in legal confinement between the point of arrest and the police station, where they will be booked for the offense for which they were arrested.
Whatever amount of evidence creates probable cause.
Someone knew the crime happened and reported it to the police otherwise there could be no arrest warrant issued.
It depends on the policy of the police department, the state the act occurs in and the circumstances. The ultimate decision lies with the State's Attorney or DA. Even if the police arrest, or delay and arrest. The decision by the prosecutor may require you to be arrested, or released.

they can order arrests to happen. professionaly no, they are not a peace officer. they are basically and judicial politician that decides the fate of someone who has been charged with a crime. however, a citizens arrest from a judge is alot more appealing than a normal person who tries to handcuff someone for making to much noise. so yes and no
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.
