Asking for the death penalty in this issue is folly. Heck, we can't even kill mass murderers in most states.
I think death is a little extreme - although it’s true that because they didn’t put Hugo Chavez to death the first time - or even the second time - he tried to take over the VZ government, he came back again and was finally successful.
But the minions probably don’t need death, since a minion without his leader is pretty harmless. They need to hide behind power.
So I think Lerner could get off with, say, 30 years, by which time I believe she’ll be in her 90s. But you’re right: everybody involved in this was committing a crime, and if they get away unpunished or with a slap on the wrist, they’ll just try it again.
