Hello Frank -

My guesses are that the tests usually include dusting for fingerprints and DNA analysis from licked areas - but what happens when your samples are covered with anthrax spores?

Glove boxes seem inadequate - It strikes me that you would have to use rubber suits in a sealed room - CDC et al have these, but what a mess -

Somebody also probably should have the great job of digging through a Florida landfill for the Enquirer envelop -

The senders (and there were probably several) were undoubtedly of foreign origin, and thus unable to differentiate the Enquirer from other media -

Ink - yes, neutron activation on ink as well -
