As Chicago prepares to host the Democratic National Convention, security services are on high alert for a variety of potential threats, ranging from violent protests to lone wolf attacks in retaliation for the recent attempt on Donald Trump's life. This marks the 26th national convention in the city, which has a history of hosting political gatherings since Abraham Lincoln's nomination in 1860. Law enforcement agencies consider this upcoming event to be one of the most secure. Over 50,000 activists are anticipated to gather in downtown Chicago starting Monday for a four-day event celebrating the Democratic Party's new leader, Vice-President Kamala Harris.

Prominent figures such as musicians, Hollywood stars, and President Joe Biden are expected to attend, and the Secret Service, FBI, and local police have meticulously planned a robust security perimeter around the downtown United Center arena. Lucas Rothaar, the FBI's lead special agent in Chicago, stated at a press briefing that while there are no specific threats, the environment is deemed to be of an 'elevated threat level.' He highlighted the broad spectrum of threats faced by the nation, including violent crime, international and domestic terrorism, and hate crimes.

The July 13th assassination attempt on Trump, which resulted in a bloody ear, led to significant criticism of the Secret Service for inadequate security at the Republican's rally in Butler, Pennsylvania. Although the shooting does not appear to be politically motivated, an intelligence assessment by federal and state law enforcement agencies warns of potential 'retaliatory acts of violence' at the Democratic convention. The report, accessed by various US media outlets including ABC7 Chicago and CNN, identifies 'lone offenders' as a major threat, driven by anti-government sentiments, political grievances, or ideological beliefs.

The security plan for the convention also considers the possibility of widespread violence, with detailed procedures in place for both scheduled and impromptu protests. Concerns have been raised about potential violent clashes similar to those during the 1968 Democratic convention, given the recent nationwide demonstrations against the Biden administration's involvement in Israel's conflict in Gaza. Harris and her running mate, Tim Walz, have faced disruptions from pro-Palestinian activists at their campaign events in Michigan and San Francisco.

The anti-war Abandon Biden movement is organizing its own convention in Chicago, bringing together 'leaders and people of conscience from across the nation.' They are planning 'decisive action against the Biden-Harris administration' due to its perceived failure to protect innocent Palestinians. Officials have prepared by clearing the schedules of numerous judges and setting up a temporary court to handle potential mass arrests. Democratic leaders are also working with pro-Palestinian groups to prevent possible confrontations.

Harris has taken a stronger stance on Israel than Biden, calling for an immediate ceasefire and vowing to 'not be silent' on Palestinian suffering. Despite these efforts, community groups in Chicago estimate that some protests could involve up to 25,000 participants. Tom Carney, a commissioner in Chicago's Department of Transportation, assured that protesters would be allowed 'within sight and sound' of the United Center. Approximately 2,500 local officers, supported by hundreds from outside the city, will be on duty for the convention. Chicago Police Superintendent Larry Snelling emphasized the importance of protecting protesters' free speech rights but warned against vandalism and violent activity, stating that such behavior would be swiftly addressed.
