I was thinking the same thing.. If you ripped someone for 12k worth of shit why in the fuck would you ever agree to meet with them after that?? What did they expect was going to happen? Hate to say it but if you're dumb enough to rip someone and then meet up with them you almost deserve to get shot. Pure stupidity.
On the other hand.. Who hands over product without counting the money?? At the very least skim through it to make sure its not blank paper.. Both sides are equally retarded. Could have all been avoided if they just counted the cash before handing over the weed.. Now one of them has less brains than he did to start out with since a portion of his brain is blown off..
I also think retaliation like that is pointless and just bad business.. I would be more concerned with getting my money back. Shooting them both isn't getting you're money back. In the end you're out the 12k and facing serious time. Fucking idiots.
