    From the site: "A hostage situation is a law-enforcement worst-case scenario, because it places innocent civilians directly in harm's way.

That makes the negotiation the most important aspect of any hostage crisis."

What constitutes acceptable criminal evidence varies somewhat between legal systems, although ideally, evidence provides reasonably reliable information that gives a more complete picture of a crime."
