Te Interconnection Between Immediate Response and Scéna Securing

While of tun considesed separately, impediate response and scene securing are deeply intercontralent. A quicht response cannot compensate for a poorly secured scene; properence may be safe from time but divisable to tampering. Conversely, a well-secured scene is useless if perishable prokazate was loss during a slow response. Effective investigations blend both into a spaniss first phase.
