One of my friends brought a metal safe recently. However he is also worried that burglars somehow know about existence of such safe on house ( either through metal detectors or some other means ). Also he mentioned that once burglars enter house and see a safe, they try to break it by any means causing much destruction.
Is this true? Is having safe in home actually inviting burglars or serves as actual security against burglars/fire etc.
What are the reasons not to have safe at home
