The statement you provided is true: the initial moments of a hostage-taking incident can be extremely dangerous. This is because those moments are typically the most uncertain, volatile, and unpredictable, with high potential for escalation or rapid changes in risk to hostages and responders. Evidence and training materials on antiterrorism and hostage response consistently highlight the danger of that early phase and the critical importance of careful assessment, rapid containment strategies, and structured negotiation or intervention plans that aim to minimize harm.
