All the evidence you quoted above was generated and supplied by a (now alleged to be a thief and a liar) Law Enforcement Agent.
Do you not think that there may be even a tiny question as to its value as evidence?
Nobody was talking about killing anyone until the DEA arrived on the scene. remember, officers found 650 rounds of ammo and 4 handguns in his home (the DEA guy, not Ross!!)when he was arrested.
As for the theft that sparked off the alleged 'hit' talk - It looks like that was stolen by our friendly inside DEA guy.
Dude, you couldn't make this shit up.
Edit: Damn! I really need to learn to either think or type quicker...
