Re: [CPEO-MEF] Fences at UXO sites

Enforcement, education, a supportive public and needed physical barriers
are all part of any effective physical security plan.  Each should be
considered as mutually reinforcing and not mutually exclusive.

Education is one very appropriate element, but patrolling,
"demonstrated" enforcement (detention and legal penalties), and physical
barriers and lights where/when needed based on an assessment of threat
(external) and risk (internal) are key elements of physical security. 
These security measures also need to be tailored, flexible and
responsive to each site.  Patrolling, enforcement and movable barriers
provide flexibility, are cost effective and can be focused on specific
sites/areas of threat and/or risk.

On the other hand, permanent administrative chain link fences and
lighting instead of field concertina with patrolling and effective
enforcement "for deterrence" are very expensive and time consuming to
install and maintain.  They also restrict general access to the public
and do little to restrict access to individuals deliberately trying to
gain access to the area.

One very simplistic example of an "attractive nuisance" precedence is
the privacy fence, regardless of height and lighting, around your
backyard swimming pool.  It is rarely an effect deterrence if you are
not home to observe and enforce the barrier.  On the other hand, a large
dog patrolling or leashed inside and a "beware of dog" sign does
significantly deter all but the most determined intruder swimmers.
