I think you'll find that:
the testimony of the police in that case
the pattern of other accusations (stalking, defamation, etc)
his on camera admissions to going to crash sites taking pieces of planes and refusing to provide them to the NTSB
my personal witnessing of some bad behavior
his being banned from airventure
that none of the people I know that have been in his circle will say anything favorable about him
that he was involved with three known incidents (corn field, electra, cub)
and many, many other experiences
has swayed many people's opinions here. Either that or he just has a cloud hanging over him and, despite being a giant among men, the world is conspiring against him.
