Security cameras in schools

All the schools have and advance with tecnology. They do the best thing because putting cameras at school can help a lot to detect everythin but not all is good. Do you think that cameras are good for schools?

On the one hand, they can be used fights. If anybody hits another guy and for this a fights starts you can know who started.Also if the school is on fire, you can know how it happened or who do it. if anyone comes at night and stealy something, cameras will detect him. Now a days a lot of people are being bulliet then, with cameras you can detect these things who does it and recieves it.

On the other hand, cameras are very visible and you can go behind a camera and breakit and it will not detect you. Another thing wrong with cameras is easy to break, you can break them with a stone. Its very easy to break.

I think that cameras are a good thing for schools because, they help a lot, but they have to do it better because if you can brke a camera driopping a dstone and you can go behind it and will not see you it's ridicolous.
