Where can I find a Seethrough Mail Box or a Bomb-Sniffing Mail Box?

Please see the end of this paragraph
from the USPS mailbox regulations:

3.3 Materials
Ferrous or nonferrous metal, wood
(restrictions apply), plastic, or other
materials may be used, as long as their
thickness, form, mechanical properties,
and chemical properties adequately
meet the operational, structural, and
performance requirements set forth in
this standard. Materials used must not
be toxic, flammable or transparent.


Sorry... no seethru

Now for the bomb sniffing part. How 
much you willing to spend?

Bomb detecting equipment falls
into 2 main categories, active
and passive. Active, such as
dogs and the cotton cloths that
are wiped all over everything.
And passive, such as the large
trace sniffers.

Well, I don't think the USPS
will allow a dog at your box.
And, um once you have the package
and are rubbing it down with 
that cloth, it doesn't really
matter, if it's a bomb anymore.

Last but not least... passive
detection. You can get that,
the cost is maybe prohibitive.
Around $750,000. I don't think
a unit like that will fit within
the sizing guidelines set forth
by the USPS either.

This page has some interesting stuff:

Check the X-Ray scanners...
You may also think of placing X-ray digital camera beside your box.
They seem to cost around $4000

I read two articles talking about three different individuals that
made clear mail box doors.  One of the articles quoted post office
officials saying that having a clear door would not be a problem in
light of recent events. Unfortunately, neither article gives contact
information for the individuals that make the doors.

American Postal Manufacturing, http://www.mailproducts.com/, is
listing see-through doors for various sizes of mailboxes.  I am not
sure if this is for residential mailboxes, but you may want to give
them a call.  They do not list prices or availability of the producty
on their website
