"Dumb criminals" refer to individuals who commit crimes in a way that is particularly foolish or inept. These criminals often make poor decisions, such as leaving behind obvious evidence or failing to plan their actions properly. Their antics can lead to their quick capture by law enforcement, often resulting in humorous or absurd situations. Many stories of dumb criminals circulate in the media, showcasing their blunders. For example, some may attempt to rob a store while wearing a mask that is easily recognizable, or they might use their own social media accounts to brag about their crimes. These incidents highlight the importance of common sense in criminal activities.
