Um. Ok, so um. At my school, in classes, its pretty safe. If I bring my macbook, I would be able to attach my macbook to the desk (there are welded loops), and the worst that would happen is it getting broken, not stolen. However, if I am traveling the hallways, my school is a bit... ghetto, and peoples stuff gets stolen frequently. How do I make it so that my laptop can NOT get stolen out of my backpack, and my backpack can NOT be taken off of me without beating me up or something?
