Why Sandra bland was arrested?

Sandra Bland was arrested in July 2015 after a traffic stop in Texas for failing to signal a lane change. During the encounter, she became confrontational with the officer, leading to her arrest for assaulting a police officer, although the circumstances surrounding the stop and her subsequent treatment raised significant concerns about police conduct and racial profiling. Her death in custody three days later, ruled a suicide, sparked widespread protests and discussions about mental health and systemic racism in law enforcement.
