Well, that is definitely a noose...however the picture they showed the other day looks a bit different.....also it’s in a different garage...something not right here.....

What's not right is the fact given the testimony of eye witnesses and a bloody picture you still don't see it.
What do you need to be convinced that it may actually be in bad taste and in fact a noose?
Should they hang someone from it to see if it works will that satisfy you.
Anyway even in that picture it looks a bit noose like and it is definitely not the normal knot used in pulley cords on garages. If that's their method its unusual.
