Lockers are designed in a way to hide their contents for a reason. Otherwise, they’d have open fronts like cupboards. Searching students’ lockers would be total invasion(侵犯) of privacy. Having a locker is more than having a place to store your stuff. A locker also gives you the freedom to keep certain things hidden. These can include harmless personal items like diaries, letters and photos. Searching lockers could discomfit students and others might make fun of them.
Yes, lockers are school property(财产). But that doesn’t give schools the right to inspect lockers as they please. While students are using lockers, they have the right to keep their contents private. Teachers could ask for permission to take a look inside a student’s locker and if the student is OK with that, then it would be fine. Searching students’ lockers without their permission would result in the loss of trust.
I doubt that students who have something dangerous to hide, such as weapons or drugs, would put them in their lockers. They would not want to risk being caught so easily.
Giving schools the right to search lockers would not help catch those who commit crimes. But it would certainly create an environment in which students would be embarrassed to have their belongings shown in public for no good reason.

Many students see their lockers as personal property. They would never agree that schools should have the right to inspect their lockers. But I think schools have an absolute right to do so.
It is the schools that actually own the lockers. Students just use them to store some of their things safely and conveniently. There are clear rules on what items students can and cannot keep in their lockers. Schools have both the duty and the right to check if students are following the rules.
I don’t think school authorities would decide to search a student’s locker unless they felt the need to do so. They might, for instance, suspect students of hiding drugs. To make sure that the process remains open and fair, only authorized teachers should have the right to search lockers. The search should be carried out in such a way as not to embarrass students in front of others.
