Transcript for 'Sons of Anarchy' Actor Johnny Lewis' Death
analyst dan abrams. What david just said there, five days out of jail. And there was a probation report earlier in the year where they said, lewis will, quote, continue to be a threat, to any community he may reside. How could this happen? Nobody's going to blame the probation officer here. After that probation officer wrote that report, he went to a treatment facility, completed it for a month. Probation officers only have so much authority. They're there to enforce the rules of the court. And unless there's a direct violation, that's really all a probation officer can do. This probation officer certainly did everything that he or she could have done. Now, police suspect that synthetic drugs could have played a role in lewis' bizarre and violent behavior. We've seen a rise in reports of synthetic drug use. What are authorities doing to combat this problem? It's a cat and mouse game. The problem is, the new ones then pop up. They're constantly trying to figure out what's the latest synthetic drug being created? What's the latest compound? How do we outlaw them? They're always trying to chase them to figure out what's the latest ones to outlaw and do the best they can. But it's really hard. Dan abrams, thank you very much.
