Night patrolman rendered defenseless by ALIENS and ARMORED aliens. Interlect exam took place on roof top of building.

I was rendered helpless, limp and dazed during a mental and physical examination; most importantly "they" (ALIENS) seemed interested in testing my IQ, a discussion ensued that my IQ wasn't suitable, other Aliens dressed in what appeared to be metal armor and/or soft silver tried to seek permission from the examiners to kill me. The Aliens left me lifeless and totally waeken so that until there departure I couldn't move or lift myself from against the roof wall, and "They"(ALIEN) didn't seem concerned about my weapons (357 M and 20 Gauge Shot Gun)...
Later, in fact a couple of years later. I reported what happen to Air Force Investigators @ NASA and Ellington AF Base and was told by the AF interviewer to not say nor tell any one about this encounter, and that someone would be in touch in the near future.
Only a sole witness in this case.  We would like confirmation from other sources.  PD
