AURORA, Colo. (AP) — The Rev. Jesse Jackson is visiting Aurora to meet with theater shooting victims and renew his call for a ban on assault weapons.

Jackson visited the apartment building of James Holmes, who is accused in the mass shooting, and said Thursday it shouldn’t be legal for someone to be able to arm himself more heavily than police.

Jackson planned to meet privately with a victim’s family and to visit a memorial outside the theater where 12 people were killed July 20.

Jackson dismissed arguments that debating gun control wrongly makes the tragedy political. He says it’s time to go from “mourning to marching” to address gun violence.

He says even people legally carrying concealed weapons wouldn’t have a chance against a shooter armed with a semi-automatic weapon.
