Consideration for Common Practices

While time is critical in many investigations, it's important to insure that investigation procedures used to minimize the time required to find evidence don't interfere with other important considerations of any investigation. The procedures must still adhere to common forensic principals such as minimizing the contamination of the original scene and the evidence, complying with rules of evidence to insure that it is admissible in court on the Federal and State levels, and maintaining the chain of custody. Well designed field procedures should have considerations for all of these commonly held practices.
