Well, there are at least three Crime Lab Photos taken of the Sniper's Nest on November 22nd prior to boxes being moved. The reconstruction done on Monday (without reference photos, it would seem) proved inaccurate in terms of the boxes by the window but afforded better viewpoints of the overall scene, so some came to be used as exhibits. A good idea; probably not. No one thought the paper bag was evidence at the time and it got moved, but testimony established where it was.
You're confusing the Sniper's Perch with the Sniper's Nest.
I never mentioned anything about photographing the Sniper's Nest.
And your notion that no-one thought the long bag was connected to the crime is massively wrong. Plenty of first responders thought that the bag was used to carry the rifle. I'm really surprised you're not aware of this. But, of course you are aware of this.
Are you also aware that the picture of the Sniper's Perch in evidence taken on Monday the 25th is labelled as being taken shortly after the assassination?
Of course you are.
Are you aware that drawing a picture of where evidence was doesn't really count?
At least you agree about Bonnie Ray's lunch.
When did police anywhere tape-record interrogations in that era? Maybe some confessions were taped. Back then, the FBI-on-down relied on notes, which usually formed the basis of reports, and the courts accepted those reports as accurate; they also allowed a law officer to testify while referring to his notes. It's not that "Nutters" think police were infallible; it's more that they understand the law enforcement of the time and not to apply the "CSI Effect".
Where do you think the DPD failed?
