The prevention of weapons,
narcotics and other contraband from entering a prison facility has
been shown to reduce violence. Attempts to cut off supply lines
have ranged from closed-circuit television in visiting areas to
increased use of trained dogs to pat-down searches of all visitors.
Unfortunately, large amounts of narcotics still find their way into
many facilities. Statistics show they are often brought in by visitors
who are pressured or threatened by prisoners.Complementing dogs,
X-ray scanners and metal detectors, the high sensitivity of trace
detection gives authorities a major advantage. As a non-invasive
tool for recognizing invisible traces of narcotics on people, luggage,
gifts and paperwork, it has a significant impact in stopping smuggling.
In cellblock inspections, their obvious sensitivity deters prisoners
from hiding or using narcotics.
Mailroom screening
Prison mailrooms can receive
gift items made out of narcotics-based materials that look and feel
completely normal, even to experienced officers. Trace detectors
combat such innovative concealment schemes as well as identify letters
sent by persons who have had recent contact with narcotics.
Trace detection is used by more than 100 prisons
