to answer my own question, it appears not very damned much.
it's been a while since they've said, ala sgt. schultz, "we know nothing!!" well, that much is horribly obvious. or, is it?
58 people dead. an additional 500 described incessantly as "wounded," .... , not "injured,," but wounded. now I don't care if the investigators cannot find their own butt cheeks with both hands (and such appears to be the case), but we should be receiving some forensic information about the wounds that killed the dead, and wounded the others.
for instance, were the wounds inflicted by the same caliber bullets, and from the same gun(s), as found with the suspect's body. this of course goes to the issue whether he acted alone, or with others.
for instance, what general direction did the bullet wound paths follow through the bookies of the dead and wounded, and where did the bullets strike them? the shooter fired at a crowd over 400 yards from him, and over 300 feet below his vantage. asumming the use of a high velocity round, it still means that the bullets followed a steeply descending arc to their targets, and the bullet paths through their bodies should reflect this, even if deeply crouched.
a final "for instance." 58 dead, another 500 wounded. not to belabor the point, but that, but that is an extraordinarily high number of bullet strikes for rounds fired. I have watched films of persons shooting ar-15's, and ak-47's, to destruction on full auto fire, and it takes a full fifteen minutes doing mag dumps to do it, and to expend only 650 t0 700 rounds in the process.
the las vegas shooter did not fire 15 minutes in full auto fire. he did not, in all probability, fire 650 to 700 rounds all by himself. yet, we are to believe he shot & killed 58 people by himself, and wounded many others. (i do not believe he wounded 500 others, but that is the word those in authority, or their spokes-people have used, the term to include the idiot press.)
yet, in the absence of some facts from these people, what else am I to believe, except my own knowledge and experience, which tells me that we are being lied to, and that information is being withheld.

p.s. why are we being lied to? well, because someone in high places thin,ks that we won't react well to being told the truth. this seems obvious to me. isis. antifa. soros. a radical faction of the democratic party. someone who didn't like country music. take your pick.
