Report lingo is not the same as his own opinion. Read the following example about Keela.
Report:
The CSI dog was therefore deployed who gave specific alert indications to specific areas on the tiled floor area behind the sofa and on the curtain in the area that was in contact with the floor behind the sofa. This would indicate to the likely presence of human blood.
Own opinion:
"She is very, very good and when she indicates there is always blood there."

The quotes I made were directly from the written submissions by Martin Grimes, in his own words.
These quotes were related only to the disputed alerts: i.e. where EVRD signalled and CSI did not.
The quotes you have given relate to where the CSI dog and EVRD signalled. This is most likely to be blood, providing both alerts are true positives.
BUT there is no indication whether the alerts relate to dried blood from a person who is still alive, or to the identity of the person, or how long the blood was there, etc, etc, which is something that MG makes clear, in his own words.
I respect your viewpoint, but, in my view, the alerts do not indicate someone died in 5A, and, in fact, add little to trying to understand what might have happened.
