MILWAUKEE (CBS 58) -- Out of state police departments are expressing worries over added enforcement during the 2020 DNC.

An issue is giving them arresting power during the four-day event.

Wisconsin law prohibits non-state officers from making arrests. 

New Jersey police say they want that authority during the event. 

Some Milwaukee leaders say the best option might be a mass deputization ceremony.

"I just hope that logistically we can do it very simply, and it doesn't take a whole lot of extra time," said Ald. Mark Borkowski. "Because we're going to have our hands full to begin with. So, if we have to, you know, a certain state has to come in at a certain point, and then another group, you know it seems kind of, logistically -- I don't want it to be a problem."

The City Attorney's Office is still looking for a way around that process through state law.
