I do not believe locker searches help fight student crime. I believe the only time locker searches truly help anyone is if there is a clear need to search a locker (ie. Someone complains of missing items and suspects a specific person). Otherwise I feel like locker searches probably get students in trouble who were not outwardly causing trouble.
Students who are determined to break the law will find a way to do it. Searching lockers for weapons or drugs is only a palliative solution. More time and money should be spent on preventing crime in the first place, rather than just looking for evidence of crimes. Students could also hide dangerous materials elsewhere.
From building schools that look like prisons to conducting locker searches, children are continuously treated more like criminals than citizens, making their path toward a bleak future even more likely. Searches do not fight student crime, but only offer disrespect to students in general. To fight student crime, teachers and administrators need to respect students first.
