People first thought there was a back door because they wouldn't release
enough info on the algorithm to give people a chance to see if they
trusted it or not. After it was all common knowledge, people examined
it and came to the conclusion that it was secure, though questions are
still around about why it was changed from 64 bit to 56 bit, which is
also why it is believed that the NSA has computers that can break it by
brute force in a reasonable amount of time, but nevertheless it is a
brute force attack.
That's how I've heard (from various sources) the whole story with DES
goes, and it seems like a reasonable one.
