The Men In Black - or MIB's as they are sometimes called are a group that supposedly show up to harass or intimidate witnesses of UFO sightings and related phenomena the government does not want the public to know about.

They usually make vague or sometimes specific threats to stop witnesses from talking or sharing information. They confiscate any physical proof of UFO related sightings -- such as photos, artefacts, or audio / video recordings.

Eye witmess reports off people that have encountered these mysterious Men in Black in USA have all described them as wearing their trademark black suit and perhaps a black overcoat. The fabric of their clothing has been described as strangely "shiny" or thin, but not silky - almost as if they have been cut from a new type of fabric.

Some report that MIB all look alike. Their often mechanical behavior has caused them to be described by some as being like robots or androids.

Their voices are monotone and their faces emotionless. They speak in a dull monotone voice, like a computer, and are dark-complected with high cheekbones, thin lips, pointed chin, and eyes that are mildly slanted.

They allegedly travel in groups of three, but are sometimes alone.

The are usually seen driving black mint-condition late model luxury cars such as Cadillacs or Lincolns. Their cars often operate with the headlights off, but ghostly purple or greenish glows illuminate the interior. Unusual insignia have been seen emblazoned on the doors and the license plates are always unidentifiable or untraceable.

Many have reported seeing these vehicles after a reported UFO sighting, alien abduction, or crop circle finding.

Some people believe the MIB are government agents. Some people believe that are extraterrestrials.

There have been reports of MIBs following people around in black helicopters.

So did the hollywood blockbusters of Men in Black 1 and 2 are did get the idea of the film from a secret society that tries to cover up eye witness reports of UFO or alien close encounters. ! !
