Abstract:
The purpose of this research was to study the work of investigating police,
to study effects related to operations, particularly in expenditures on murder cases and
to propose guidelines for improvements in investigation operations.
Ninety-eight commissioned officers, being inspectors allocated to 88
metropolitan police stations, investigation superintendents of division 1-9, and special
operation division (191), were respondents. Statistical applications were percentage,
mean, ANOVA and MCA (multiple classification analysis). Findings were as follows:
The personal backgrounds of the population e.g. age, rank, years of service,
and experience in investigation were variables differently affecting opinions of
expenditures on murder cases. The reason was that age, rank, years in services and
experience in investigation, gave knowledge and training in investigation procedures.
Officers with age, rank, years in service and experience in investigation perceived that
large expenditures were likely to bring success. However, the Royal Thai Police
Office was unable to afford such expenditures causing investigating officers to
personally subsidize the job. It has become a critical problem in performance in crime
prevention and suppression. A well as expenditures for probes, there were other
elements i.e. new knowledge and technology were not yet applied in every case on
account of scarcity of support.
Therefore, personal backgrounds, factors and expenditures affecting
investigations, particularly murder cases, are statistically significantly interrelated and
affect achievement in investigating murder cases.
Recommendations:
1. The Royal Thai Police Office should allocate funds for probing which
would leverage effective performance.
2. The government or allied countries equipped with investigation funds
and technologies should encourage and support officers more to learn and to gain
knowledge in these affairs.
