FBI and the office of homeland security are putting all law enforcement agencies on alert this Fourth of July.
From coolers and bags left unattended, to garbage cans and public buildings.
Police will be keeping a close watch on it all to prevent possible attacks on Rockford’s Fourth of July parade and fireworks display.
Rockford police have divided the downtown area into eight patrol sections marked and unmarked units will be patrolling streets, while Winnebago County sheriff's police and the Rockford fire department take to the waterways.
Rockford police say the chance of an attack is very slim, but are worried about people drinking too much alcohol, shooting off fireworks, anything to create panic in a large crowd.
More than 100,000 people are expected in downtown Rockford for the Fourth, it's a celebration the mayor's office and police department say will be safe, even though major law enforcement agencies are putting out alerts.
