This section sets the tone for the rest of this book. The management of the threat of violence is a highly individual matter that cannot be decided unilaterally by any official guidance. But all management requires a framework within which practitioners have to work, only going outside it under exceptional circumstances. In Chapter 1, Eric Baskind makes a bold attempt to bring all together with the suggestion of a common set of guidelines, as violence can show itself, often Medusa-like in its sudden venom, in every possible setting. So, it is wise to have a common policy of management. But we are not there yet, and Chapter 2 tells us exactly where we are at present in terms of legislation, a subject that changes often and which depends on the locality. This is an excellent aide-memoire to those who organise management programmes and need to ensure that they are both legal and justified.
