Samenvatting
As mentioned above it is planned to undertake research into the effectiveness of some of the more central deterrent activities of the plice, such as conventional patrol surveillance and criminal investigation. The consequences of improvement in security will continue to be studied and it will also be necessary to mount what are likely to be difficult evaluations of those activies (e.g. work concerned with school liaison, juvenile bureaux, community relations) which are designed to raise public commitment to the law.
