Background checks generally cover credit history and public records (to include warrants, court cases, and judgments).
If they are entered into the criminal justice computer system they will show up on a background check.
If there is a warrant issued, it stays open until resolved/you are arrested. Arrest warrants do not have time limit.
To prove citizenship or for security and background checks.
The purpose of background checks is to investigate a person's suitability. For positions involving working with vulnerable groups, a background check will most certainly focus on issues relating to child abuse. Even if the role is not working with vulnerable groups, child abuse is a very serious crime and will put off most employers.
No you may not. Most likely the state will place a child with next of kin, if the other parent is unable as well. But depending on what the warrants are for, after you serve your time. You will most likely get the child back. Hope this helps.
No. They do not.
The FBI can be very in depth. They will even interview people that knew you when you were a child. If there is something to find, they will find it.
An educated guess: Yes, an officer has an obligation to report crimes or arrest fugitives of which he has knowledge, unlike an average citizen. If you or anyone is connected to the crime (accessory or helping hide a crime, such as harboring a fugitive or obstructing justice) or have a mandatory duty to report certain offenses (e.g., child care provider or teacher who knows of child abuse), that's different.
Sure; background checks are not nearly that comprehensive.

The person to whom the checks are written.
