I think so because it would make all schools safer and students safer. If the police check for weapons and drugs students will stop bringing in violence and deaths will occur less. People say no because they will get into their privacy but if you don't have drugs or weapons you have nothing to hide. :) SAY YES
Schools should be able to look through students' lockers. When there is a potential threat in a school--for example, perhaps suspicion of a student bringing in a weapon or drugs--time is of the essence to try and find out for sure whether or not the suspicions are true. Sometimes we must sacrifice some freedoms (like privacy) in order to guarantee safety.
There could be very bad things in that students locker and that no body knows about it. They could be putting kids in real danger if they do not do the locker checks. Such as weapons, drugs, and other things. Also the mess that could be in their locker. Also crumbled papers.
I know that the fourth amendment states that people can do basically anything that want as long as it wasn't outside the law, but what if they have drugs or weapons or inappropriate material? Somebody could be slippin' "playboys "or marijuana or even a knife, but people don't like their locker searched, so don't put personal or bad things in the locker in the first place! :/
They are searching through the students property without consent. Did the school get a warrant for the locker to be searched? Most likely not. If the student doesn't want the locker to be searched then it shouldn't be because that is their right under the constitution. Fourth amendment states
The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no warrants shall issue, but upon probable cause, supported by oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.
And a dog scratching at a locker isn't probable cause.
