yes, the evidence shows that Z did NOT strike or injure TM( prior to the gun shot)... the evidence shows that TM did strike and injure Z.
that, in and of itself, contradicts your claim of Z "starting a fight"...the evidence corroborates/supports Z's story.. that's really all there is to it.
Anyone wondering what I'm talking about start here:
The Psychology of Persuasion
The scorecard to date:
1-He was in an uncorroborated domestic incident in which his GF dropped the charges.
2-He was in an alleged altercation with an individual that claimed he threatened to kill him (no corroboration, police did not seek charges)
3-He is reported to have been in an argument with his girlfriend, reported to have thrown a wine bottle in her general direction but not reported to have struck her with the bottle or any part of his body. The woman in the situation was arrested on an unrelated charge and while being arrested, made the allegation to officers that 5 days prior, the reported domestic incident occurred.
By all means...rehash the Trayvon Martin incident.
