Delivery service companies and businesses that receive parcels daily concede that the infamous Unabomber and those like him have an advantage when they play their deadly game. There are literally too many packages and envelopes to check carefully, and the Unabombers of the world have time on their side. The bomber can afford to wait.
Time goes by and people forget the last bombing and then, boom, it can happen again.
Federal authorities believe it was the Unabomber who struck again Monday afternoon in Sacramento. But those who do the sending and receiving said Tuesday there are limitations to what they can do to check the safety of all packages. We do have our own precautions and response manuals, but we handle so many packages. On a typical day, UPS offices throughout the U.S. handle about 11.5 million packages. Industry analysts said that huge volume is the heart of the security problem facing delivery companies.
