JEFFERSON CITY — Participants at a rally at Missouri's Capitol call for a moratorium on the death penalty until 2012 so it can be studied.
Among those at Wednesday's event was attorney Sam Millsap, a former prosecutor, who says he might have sent an innocent man to the death chamber in Texas.
The Missouri legislation would create a panel to review whether the death penalty is applied fairly and whether it does not wrongly sentence innocent people.
At least two other states have set up similar commissions, and New Jersey abolished its death penalty in 2007.
Just after the rally, the state Supreme Court heard an appeal from a Platte County man sentenced to death, who argues his lawyer should have introduced more evidence concerning his brain injuries.
