"Stupid criminals" refers to individuals who commit crimes in a foolish or careless manner, often leading to their quick capture. These criminals may leave behind obvious evidence, such as fingerprints or surveillance footage, or make poor decisions that draw attention to their illegal activities. Many stories of stupid criminals highlight their lack of planning or common sense. For example, some may attempt to rob a store while wearing easily recognizable clothing or use their own social media accounts to brag about their crimes. Such actions often result in their arrest and serve as cautionary tales for others.
