It was not possible for the Schindler's to either inject something, or remove blood from TERRI during their visit?
I don't think you have, because despite all your remarks to others, you are not as open-minded as you would like to think.
The Schindler's are not allowed UNSUPERVISED VISITS. They are only allowed in with a POLICE OFFICER to watch them.
So, now, tell me the COP did it.
