If-----------e.g.!-----------Mr J Ruby's prints were found on the same toothbrush as Mr Oswald's prints, you don't think that might be indicative of something interesting?
Cart before horse, Mr Nickerson! Until they do the fingerprint test, they can't know for sure whether the toothbrush is someone else's. See? Logical!
If Ruby's prints were found on the two curtain rods might that not be indicative of something interesting?
No, that would not be comparable.
Why not? Maybe Lee,or Harvey, or Harold,or whichever one of the three, messed up and left those curtain rods in the garage when he was supposed to have them planted at the TSBD.
