Asylum you missed the point.
To use your example, THE Truth is that you shot someone repeatedly in the head with the intention of killing them, you're motive being say they pushed in front of you at a bus stop.
Now here are a couple of examples of various 'truths' which people might take from that incident:
Asylum was framed by a jewish media conspiracy.
Asylum is indicative of the hoodlums over-running society today.
Asylum is a hero who refused to cop it on the chin and did something about it instead.
Asylum just happened to be holding the gun and it went off of its own accord.
Asylum is criminally insane and can't be held responsible for his actions.
Asylum shot someone because they pick-pocketed his wallet when they pushed in front.
Asylum, etc etc etc.
These 'truths' all bear some connection to THE TRUTH but are not infact the objective TRUTH they are varied subjective 'truths'. That is to say they are perceptions of THE TRUTH coloured by predisposed bias etc etc.
