Today, the international community make every effort to suppress security crimes, to
provide numerous institutional strategies and to prevent security crimes such as the terrorism
and spy. Particularly, developed countries in the field of security are strengthening related
legislation under new-security conditions. Things work a little differently about security
crimes because the nation’s benefit and protection of the law is the basis of individual benefit
and protection of the law under investigation procedure of the security crimes. Therefore
they have policy that permits major investigative agency under the arrest and detention
procedure(e.g. security and communication monitoring ...).
Criminal procedure’s improvement and reinforcement are very important for events related
security. But, The investigation procedure between criminal offense and security crimes
makes no odds in the Korea. Continuance of such a national mood will accuse of not
responding appropriately in preparation for new-security conditions recently.
To revise with international best security legislation, We should institute a proper
registration system in Korea’s situation. This study have been discussing how to improve
related legislation under new-security conditions through the cases analysis of the arrest and
detention procedure in Korea.
