This from the ACLU article:
"In 1998, people convicted of drug offenses constituted almost one-fourth of state prison inmates and over half of the inmates in federal prison. While African Americans reportedly make up 13% of the nation's drug users, they are almost 60% of those in state prisons for drug felonies. "
And this the VERY OPENING of the Atlantic article:
"Correctional officials see danger in prison overcrowding. Others see opportunity. The nearly two million Americans behind bars—the majority of them nonviolent offenders—mean jobs for depressed regions and windfalls for profiteers"
Anyways, what exactly are you inferring from this? That those who commit drug felonies are not violent offenders? Even if that were true, your "citations" still don't support the assertion of the gp that "Most people are in prison for pot-smoking and non-violent offenses".
"Most - non-violent offenses".
Quotation: the majority of them nonviolent offenders
majority - nonviolent offenders
I don't know how else to spell it out.
