Washington: President Barack Obama plans to put in place new restrictions on the use of military equipment by police departments, following unrest in US cities over the deaths of black men at the hands of police officers, the White House said on Monday.

Obama will ban police use of equipment such as explosive-resistant vehicles with tracked wheels like those seen on army tanks, the White House said in a fact sheet. For other types of equipment, such as MRAP (mine-resistant ambush protected) vehicles and riot shields, departments will have to provide added justification for their use.

Obama will announce the steps, which are the result of an executive order, during a visit later on Monday to Camden, New Jersey, where he plans to push efforts to encourage trust-building between police and the communities they serve.

The fatal shooting of unarmed teenager Michael Brown by a Ferguson, Missouri police officer in August was followed by a string of highly publicised fatal encounters between police and black men, including Walter Scott who was shot by an officer while fleeing the scene of a traffic stop in North Charleston, South Carolina.

Last month, violent protests erupted in Baltimore after 25-year-old Freddie Gray died after sustaining spinal injuries while in police custody.

Protesters in Ferguson felt the methods used by police to prevent the demonstrations from turning violent were excessive, and the Justice Department has since launched a review of Saint Louis County law enforcement’s response to the unrest.

The turmoil in Ferguson and Baltimore also highlighted divisions between black and white Americans.

In a Reuters/Ipsos poll taken after the protests in Baltimore, 69% of respondents said America has a serious issue with race. Nearly three-quarters said there is more racism in the United States than the country is willing to admit.

In the aftermath of the Baltimore riots, Obama has been speaking out more about race, including in a speech in the Bronx on increasing opportunity for young minority men and during a panel discussion on poverty in Washington.

‘Race issues have been more present over the past year for this country. We’ve seen, since Ferguson, issues that have been bubbling up in communities becoming much more present,’ said Rashad Robinson, executive director of colorofchange.org, a group that aims to strengthen the black community’s political voice in America.

Robinson has met with Obama to discuss the issue.
