The White House will revisit a 2015 ban on police forces getting riot gear, armored vehicles and other military-grade equipment from the U.S. armed forces, two police organization directors told Reuters on Thursday.

Shortly after the recent shooting deaths of police officers, President Barack Obama agreed to review each banned item, the two law enforcement leaders said.

That could result in changes to the ban imposed in May 2015 on the transfer of some equipment from the military to police, said Jim Pasco, executive director of the Fraternal Order of Police, and Bill Johnson, executive director of the National Association of Police Organizations.

Last year’s ban came after a public outcry over police in cities, such as Ferguson, Missouri, using military-grade riot gear and armored vehicles during protests against police brutality.
