Men in Black:

British ufologist Nick Redfern discussed his research into the Men in Black (MIB) phenomenon, in which he looked at numerous cases from the start of UFO sightings to the present day.

The first report of Men in Black was associated with Albert Bender, who was studying UFOs in the early 1950s and formed a popular group called the International Flying Saucer Bureau. But then, he suddenly shut the organization down after he was visited by three men wearing black suits who told him that he was getting too close to the truth, and if he knew what was good for him, he'd leave the subject alone.

Later, researcher Gray Barker popularized Bender's tale, and implied that the Men in Black were government agents, Redfern detailed.
In many of the MIB accounts, witnesses describe the visitors as having somewhat odd appearances and behavior, including bulging eyes, being very short, sometimes lacking in emotion, and suddenly disappearing. Their goal always seems to be intimidation, which is typically accomplished with veiled threats, said Redfern, who added that he found it curious that people invariably allowed these strangers into their homes, which indicates the MIBs might employ a kind of hypnosis.

Redfern has concluded there may be more than one group behind the MIB phenomenon. For instance, there is documented evidence that government agents have visited people who've reported UFO sightings, yet some of the paranormal aspects to MIB visitations suggest there may also be alien/hybrids making their own visits to determine how much people know about them.

Joshua P. Warren proposed an interesting theory to Redfern-- that MIBs may actually be time travelers. The reason they wear the black suits is because this look will fit in in many time periods, and this might also explain why the cars they drive are sometimes out of date, Warren said.
