they used to take fingerprint of i believe of thumb and index finger before 9/11 when travelling to US (this is part of US-VISIT program). If you shipped a few small shipments to the US (below 10g) of which maybe a few got intercepted what is the chance that these intercepted packages got fingerprint checked and do they run fingerprints directly through the US-VISIT database or is/was there some protection of these databases (ie. use of databases for national security or if you travel into the US can these fingerprints be accessed and used by all LE)
If gloves are worn then there will be no prints on the packages to run through any databases.
Or am I missing the point here?
