There is no way a BLOB would have remained on the outside of the silencer for 3 days and it wasn't tested because it wasn't there!
That is your opinion that blood that dried would have fallen completely off. Either the blood was never there and Ann was mistaken, Ann made it up for some reasons though it serves no purposes or the blood fell off before it was turned over to the lab. In any even this has no bearing at all on the blood that was tested by the prosecution and the defense.
In understand your argument but it is feeble.
Your argument is like the following:
There is a hit and run car accident. The car that was struck contains damage that demonstrates the car that hit it was a white toyota. The paint chips left on the car match a toyota that had a custom paint job. The location of the paint chip tested matches exactly where said toyaot would have rubbed against the car in the collision.
There reportedly was another white paint chip in a different location that vanished before it could be tested. There is speculation such chip was planted but no proof that it was.
Speculation about this possibly planted chip is then used to suggest that the evidence that there is no eidence to suggest was planted is suspect.
Does this suspicion erase the fact that the actual damage to the car came from a white toyota? No the damage is consistent with such. The paint chip tested was consistent with such and matched to a specific white toyota.
If you want to challenge this evidence you need to do so directly. Round about attacks on missing paint chips they may or may not have been there accomplish nothing at all.
Did the lab shave the silencer? Because apparently it sprouted a hair also - which (and I know you won't believe this folks) but is disappeared - go figure!!
The hair could have resulted from the murders, it could have attached to the suppressor int he closet as it was being put away, it could have been planted. It might even have been a figment of their imagination or a lie. You have no way to establish it was planted or a lie as opposed to attached during the murders or after. It could even have been stuck there prior to the murders.
Sheila's blood 'type' was found or rather just the AK1 enzyme, so it was 'attributed' to Sheila. They found none of her DNA later though!!
That is how you determine blood type you look for markers that distinguish them. They found the markers related to her bloodtype. Some markers were shared with her parents others were not.
However it got there, I wouldn't like to say as I'm not in the habit of planting blood in silencers but I guess those in the know would, well - know!
Well this is the important part becuase if you can't even estbalish how they would plant it you have no hope at all of establishing any likelihood that anyone did so.
What would the statement entail? Well, who was there for starters! How many witness's witnessed the finding of the silencer and what they actually saw on it and where they were when they saw it! because in the space of only one month they had all seemed to forget such fundamental details of things like - who was there at the time!
it is common for people to forget things after time passes.
To prove the blood was planted requires proving a series of things from knowing how to do so to where they got the blood from and eliminating blood from the weapon which means the fmaily alone were NOT in a position to carry out such alone. It requires a grand conspiracy.
Rational people find such a grand conspiracy hard to swallow but you have failed miserably in establishing any evidence of such.
You need people to recognize they would need to spray blood inside the suppressor instead of just dripping it in, finding a tool to use to accomplish such, obtain blood that was group A and to actually transfer it, and also to arrange for the blood in the rifle to be eliminated and disposed of without any receord of ever having been found.
You have provide no evidence that suggests any of this happened.
You believe it simply because you want to not because there is an evidence to suggest it happened.
