"Did the Sackler family commit a crime here?"Arguably yes. It's not possible here to properly cover the many issues involved from longstanding narcotics law, international treaties on narcotics, etc. to the duty of care the Sackler family should have exercised for those who consumed its opiate products, and so on. That the Sackler family did this through its company Purdue Pharmaceuticals is immaterial, as they not only knowingly allowed widespread proliferation of these narcotics but also actively encouraged the pushing of said narcotics. Moreover, the Sacklers made many millions of dollars from the hapless and desperate consumers who consumed its addictive opioids—many of whom have died; the estimate of numbers is in excess of 100,000. (If anything, a confiscation of their wealth ought to be justified under proceeds of crime legislation.)
What's truly relevant here is that both the Sackler family and Purdue Pharmaceuticals not only had both access to expert knowledge about opioids, their addictive properties and the longstanding protocols for their control, administration and use thereof but also they were actually in possession of such expert knowledge.
(Note: this is a non sequitur, as it would NOT have been possible to be a manufacturer of narcotic drugs within the USA and NOT know these facts by second nature and yet they deliberately pushed these drugs onto the market in an extremely irresponsible way (in fact, people within Purdue casually and callously joked about the fact).
The fact that this was allowed to happen and that Purdue was allowed to continue doing so for so long is a separate matter, and for that, the FDA holds considerable responsibility.
Remember, the addictive properties of opioid drugs is extremely well known to the medical fraternity, the pharmaceutical industry and to many, many others and it's been so for a very long time. It's absolutely no secret—in fact, it's been very well documented since the Civil War (when hypodermic needles first became available and opioids were given I.V. to injured soldiers for pain relief many of whom became severely addicted). This knowledge resulted in International treaties in the early part of the 20th Century and it meant that many countries introduced severe penalties for peddling narcotics—from many decades to life in jail, and in some countries the death penalty.
For a company such as Purdue Pharmaceuticals to be little more than a street pusher of narcotics through its negligent misuse of its position of responsibility by not having most stringent protocols in place is about as irresponsible as it gets. As mentioned, upwards of 100,000 people have died as the consequence of the Sackler family and Purdue Pharmaceuticals irresponsible, negligent and reckless actions—actions that were committed out of sheer greed of absolutely the worst kind.
In my opinion, just confiscating their financial assets alone isn't enough, they too ought to be in jail along with the other pushers of narcotics.
That the Sackler family can actually negotiate its way around what's happened is also a travesty of justice.
