Today, May 8, 2007 Sir Florentino taught us how to swab a gun and he told us the purpose of Cotton Swabbing. The purpose of cotton swab is to determine presence of gun powder in an evidence firearm. I, Isabelle and Mark Carlo tried one by one. We cotton swab one gun by putting a cotton on a barrel then use a stick to push the cotton to pass the barrel and get gun powders. We did cotton swabbing on the barrel twice and we also cotton swab the holes of where bullets are place. The agency will conduct further examination on the cottons used in the cotton swabbing.
