When a criminal commits an offense, one of their primary goals is to avoid being caught by authorities. This motivation will drive criminal offenders to take precautionary measures. Precautionary acts can be described as behavior displayed by an offender (before, during, or after the commission of a crime) with the intention to confuse or hamper forensic efforts with the sole purpose of concealing a crime, their involvement, or their identity. Philip Chism is an example of a case in which precautionary acts were a part of the criminal offense.
