THERE WAS A DEMONSTRATION IN BRIDGE PORT WHERE PEOPLE GATHERED INSIDE FOR A DNA PARTY. MAYOR JOHNSON IS CALLING THE DNC A BIG SUCCESS. >> >> Reporter: FIRST LET'S LOOK AT THE NUMBER OF PROTEST ERS. THE CITY WAS PREPARING FOR 20 TO 25,000 PROTESTERS. BUT DPC SAYS WHAT WE ACTUALLY SAW WAS MUCH FEWER THAN THAT.

PEOPLE WERE WORRIED ABOUT HOW CPD WOULD DEDICATE SO MUCH OF THEIR MANPOWER TO THE DOWNTOWN AREA AND STILL KEEP UP WITH CRIME IN THE CITY. CPD DIDN'T SPECULATE AS TO WHY A REDUCTION IN CRIME. BUT THERE WERE JUST TWO ARRESTS YESTERDAY. INCLUDING THIS MAN WHO WAS TAKEN IN FOR OBSTRUCTING TRAFFIC AFTER A LONG INTERACTION WITH POLICE. >> YES, THERE WERE INDIVIDUALS WHO WERE ROOTING AGAINST CHICAGO. AND THEY WERE ROOTING FOR VIOLENCE AND CHAOS. IT'S NO DIFFERENT THAN WHAT GOVERNOR ABBOTT IS DOING. >> I SPOKE TO THE MAN WHO WAS ARRESTED
