Yes they will. Why the fuck would they not. If a vendor is shipping drugs LE wants to bust them. If they don't use gloves, they will have fingerprints all over the package. If LE gets fingerprints off the package, and find a match for the vendor, then the vendor is busted that easily. Fingerprinting intercepted packages is possibly the easiest way to bust most people who ship drugs. You are god damn hopelessly deluded and quite likely fucktarded if you think LE will not fingerprint intercepted packages. USPI has an entire lab dedicated to forensics on intercepted mail. You live in a total fantasy world and obviously have not got the slightest god damn clue about reality if you really think that they will not fingerprint packages, so please do yourself a favor and shut your stupid ass mouth before you make yourself look like the biggest idiot in the world, again.
