No shit....that sucks. However,,,in my world you are fortunate that they came...and they left....and they didn't take you with them.
Just cut the guy out of the mix. You don't need the cops coming for ASSault charges and more. Your buddy could easily make a call/visit to see the pigglies if (after) you beat his ass....cus that is another (Felony) crime and he will be pissed.....like you are....and he knows too much to put yourself in that position. At that point....he has nothing to lose and you have everything to lose. Let it go and learn the lesson or shit may get much worse.
"All good things must come to an end....it's the same wit the Wildwood Weed" LOL. Some will remember that....some never knew what it was all like.
I had a couple of packages go awry myself. Clones and bud. Got a letter saying they though there was "contraband" in the package and I had 30 days to claim it/dispute the claim....the package would be "destroyed" . (smoked by some guy at the PO) Sure thing...I'll be right down.
That was the end of that fun. "Live to grow another day". I haven't sent "packages" since.....but letters are not scrutinized unless white powder falls out of 'em.....so I still take care of my sick peeps. FWIW....quite a bit of bubble will fit in an envelope. Just make sure you use 2 stamps. LOL
