I expect there will be more deaths connected to the product and KL. Still- I imagine the crucial element will be proving that KL sold the substance knowing what the person intended to use it for. I bought from IC. I received a police check and later, a detective got in touch. So yes- they are trying to build a larger case against him. But it's like I told the detective- I made no mention of suicide when I bought it. As far as he knew, I was purchasing it in good faith to cure meat. As I said to her- in terms of my case- it would be like trying to sue a hardware store for selling someone some rope. I think it will come down to how open (and honestly- naive) he was about corresponding with people on how to use it to CTB.
Of course- the next more worrying step is they could start looking in to how people know about it and how to take it. Obviously, I didn't want to tell the detective about this place but I imagine they already know. I wonder if they have the resources and incentive to go that far. I wonder what they would define as assisting a suicide. That's one reason I try to avoid method talk now. Another being that I don't know enough to give advice.
