there were undoubtedly many many people who's lives were destroyed through easier access to hardcore narcotics ... that IS harm ... law or not law ... technicality or not technicality ... *ethically* the guy should burn ... (assuming actual evidence exists linking his involvement which , of course, there was) ...
You are entitled to your opinion, but BTC users tend to be libertarian and thus think governmental babysitting such as banning drug use/drug dealing is immoral. I don't tell other ppl what to do w/ their bodies so would hope for the same in return. Banning drug use sounds like something out of a previous century.
The issue with allowing people to do...well whatever the choose with themselves is that most people don' have the knowledge(Well all people), to make the right decisions most of the time. We are bound by our own biology, so we cannot have 100% freewill, knowledge, freedom etc(If we did, then you extremist Libertarians would be right, but since we don't the vast majority of you are wrong).
An example is this: A uneducated person is persuaded by a peer to use Opium because in the short term it gives "benefits" such as relaxation, pain relief, reduced anxiety and impaired alertness and coordination. The person doesn't know any better because of his ignorance, so he goes ahead and takes the drug. Several years past and his body becomes more and more tolerant to the # of doses he has been taking, so he ups it continually, all the while his body becomes more tolerant and he is severely addicted(A wide variety of "hardcore" drugs are extremely addicting, to the point that after a certain period of time using them, your body physically depends on the drug or you will go into withdrawal and possibly die). The person gets to the point that he gets cancer, heart attack, has an overdose, and dozens more(A lot of which are fatal).
Overall, my point is that people are not limitless creatures that know all there is(such as the effects or outcomes of doing this and that, etc), so, there has to be certain rules that people must generally abide by, or risk destruction of themselves and communities, so no, drugs should not be legal(mostly because of the dependency/highly addictive part, where after certain longterm use your body physically depends on the drug).
