Fair police Chief James Bruno says about 100 event support staff members have received additional training in traffic control, building and state security and patrolling the grounds, among other duties.
Bruno says the public safety staff are in addition to about 100 sworn police officers at State Fair Park.
WISN-TV says police have also added about 40 additional security cameras bringing the total to approximately 185 camera shots around the fair grounds.
Bruno says no weapons, including guns, knives or electronic control devices, are allowed on the grounds. In addition, fair policy doesn't allow anyone under 18 to enter the event after 5 p.m. without a parent or a guardian who's over 21.
