Someone stole the table in the library. You can ask the manager or the school leader.

The school library is equivalent to a public place. When it was stolen, the manager just helped you, not responsible for you. Ps library should publicize the slogan that its own things should be properly kept for a long time, because the library is not responsible for stolen things, but people always take it out on the library and think that the library has the obligation to protect its own things. In fact, there is really no supervision at best. I don't know what pure law thinks.
