The Secret Service will be in charge of security of what is being referred to as the hard perimeter, which is the inside of the United Center and the immediate area surrounding it.
It will be up to CPD to secure the soft perimeter, meaning everything outside, and that may be where the biggest challenges lie.
So not only is it CPD's job to ensure that all the planned protests go off peacefully, but they do have responsibility, in conjunction with the Secret Service, for manning and securing the rooftops of all the buildings outside of the hard perimeter which may have a line of sight to the United Center.
CPD provides update on DNC plans after Trump assassination attempt
CPD Supt. Larry Snelling reiterated that planning for this event has been going on for over one year, and that planning includes preparations for every scenario.
Snelling also said that he is in contact with his counterparts in Milwaukee so that any lessons from the RNC this week can be applied in Chicago.
One thing to note is that it is still not clear where the hard and soft perimeters will be. The Secret Service is expected to release the exact boundaries in the coming weeks.
