Heavily armed security boats patrol winding Milwaukee River during GOP convention
Security planners for the Republican National Convention have had to contend with the winding river that snakes through downtown Milwaukee and near the Fiserv Center convention site. Roughly half a dozen police departments, along with state and federal agencies, have boats patrolling the river 24-hours-a-day until the convention ends this week. Usually it's kayakers and tour boats in the summer, but this week the summertime scene on the Milwaukee River has taken on a solemn tone. The water way is eerily quiet with around-the-clock patrol boats, some with heavily-armed officers.
