Acme Police Whistle

Origin
Acme police whistles were designed to be heard from the distance of one mile away from the user. This was to alert other officers of trouble, or to be heard over the sound of car traffic.

Usage
When the user blows into the whistle and points at his/her target, the area surrounding the target will freeze in time. However, the time-stopping effect will only last as long as the user is blowing into the whistle. If the user falters for one second the effect will stop. This effect has a maximum range of exactly one mile.

Collection
This artifact, along with several others, was collected from a private auction of police antiques.
