“People saw him on the roof for 90 minutes before the shooting and did nothing.”
He climbed onto the roof about six minutes before the first shot and people started yelling about it right away.
“The FBI destroyed his body in record time to hide evidence.”
The autopsy was performed the day after the shooting, and FBI agents Jill Wolfe and Brian Johnson were present. Autopsies usually last two to four hours and the body is released to the next of kin within two or three days. The fact that his body was held for ten days indicates a high degree of thoroughness collecting additional evidence. At this point the FBI released the remains to the coroner, and the coroner gave permission to release the remains to the family. The family chose cremation, not the FBI or the coroner.
“Witnesses said he was tweeking, pulling at his hair and obviously on drugs.”
Autopsy found no traces of drugs or alcohol in his system. If this did actually happen – and there is only one unverified source – it could have been a manifestation of agitation or nerves, but it is impossible to say.
