CHICAGO -- Chicago Police arrested 19 men and 47 women who were protesting outside McCormick Place on Saturday.
Saturday marked the first day of the 122nd International Association of Chiefs of Police annual conference at the convention center.
Police say the protesters face misdemeanor charges of obstruction of traffic by a non-motorist.
The protesters are demanding fair policing practices and a shift in the way police engage with black communities.
Mayor Rahm Emanuel and Chicago Police Superintendent Garry McCarthy welcomed thousands of chiefs and other law enforcement from agencies across the country.
Mayor Emanuel outlined Chicago's strategy to strengthen community policing. "We don't just patrol a neighborhood. We're part of a neighborhood. If we have that philosophy and implement it, we will build trust between the community and our law enforcement community. ... This has been a difficult year, but all of us who entrust and expect the type of public safety we receive need to speak up on behalf of the law enforcement community who everyday are doing their job: building, protecting and serving the residents of the city of Chicago," said Emanuel.
President Obama will be in Chicago on Tuesday to address the conference.
