Your post is response to 'Tonya tried to kill someone'.
She did not, and Adam should have been corrected.
Killing someone is not the same as assaulting someone. And assaulting someone is not the same as being complicit in an assault - and it should be noted that Tonya's level of complicity in the assault (getting information about where Nancy practiced)
As to getting a second chance, I think the poster referred to in life, not skating?
Tonya definitely deserves a second chance in life. Assault does not usually merit a life sentence, but she received one - a lifetime ban.
