POST SECURITY, LAW ENFORCEMENT AND TERRORISM
During the time of the 513th Camp King was garrisoned by MP's assigned to the 513th, Post Security was tighter. The post was a closed post and remained that way until closure.
According to Don
Burgin, a former MP on the post:" While I was an MP there,

On many occasions bomb threats would be called into the schools. The building would have to evacuate until the MPs and the German Police completed their search. It was not uncommon to find that students wanting to avoid classes had called in the threats.
During periods of tension, post security would be heightened until the situation diffused. Once the situation passed, it reverted to the status quo. Security on the post was conducted by unarmed UPs (Unit Police). They checked IDs at the gate. Other than that, it did not appear that there was any other official security.

Law Enforcement was the responsibility of a unit garrisoned in Frankfurt. MP presence on Camp King was not that common.
If a soldier or dependent committed a crime or breach of peace, it was disposed of through the military community. If the German Polizei were involved, it was usually turned over to the Americans to handle, according to the Status of Forces Agreement. In some instances, though, the German Government could retain jurisdiction.
