The situation in downtown Chicago was rapidly devolving last Saturday afternoon when a young man in a grinning “Joker” mask allegedly walked up to a police SUV, set it ablaze, then sat down on the curb to roll himself a cigarette.

Hours later, a downstate man was arrested in the Loop allegedly with homemade explosives in his car after police said he posted videos of himself on Facebook looting stores and saying he’d come to the city to riot.

But the picture that has begun to emerge from court records in both Cook County and U.S.

But when federal arson charges were brought Tuesday against Timothy O’Donnell, a 31-year-old visual artist accused of setting the blaze, that assumption appeared to fall apart.

“He’s a big supporter of the police," said Leonard, who plans to ask that O’Donnell be released on bond at a detention hearing on Monday.

Among them was Amber Peltzer, who was arrested last weekend after officers allegedly saw her peering from the shattered doorway of a South Loop bar.

A case brought in federal court in Minnesota last week accused Matthew Rupert, of downstate Galesburg, of posting internet videos of himself participating in the looting and rioting in both Minneapolis and Chicago, including furnishing homemade explosives to others in the crowd and inciting them to toss them at police.

“Light that b--- and throw it at them,” Rupert said on one video shot in Minneapolis, according to the charges.

On one video, Rupert could be seen entering a downtown Chicago store and searching the empty cash register, and going into a convenience store that had been broken into and putting cigarettes and other merchandise in his backpack, according to the charges.

At the time of his arrest on the federal charges, Rupert was facing pending charges of possession of methamphetamine in Knox County, records show.

After Galesburg police in February posted on Facebook that Rupert was wanted on drug charges, Rupert commented on the post using his own profile, calling police “petty” and “bums.”.

Officers broke at least three of the car’s windows with batons, according to Wright’s family and the video, and pulled some occupants out of the vehicle.

Police spokeswoman Kellie Bartoli said Wright was placed into custody and charged with disorderly conduct after she was observed by responding officers “assembled with three or more persons for the purpose of using force or violence to disturb the peace" — a direct quote from the city’s disorderly conduct ordinance.

The Cook County state’s attorney’s office, which is not handling Wright’s prosecution since it was brought as a city ordinance violation, said Thursday it also is investigating the matter in conjunction with the FBI.

All week, Cook County bond court was slammed with new cases ranging from the seemingly petty to the deadly serious.

From Friday evening, May 29, to Monday morning, June 1, police in Cook County brought more than 250 cases to the state’s attorney’s felony review unit.

Regardless, the dockets at Cook County bond court were packed all week, each day bringing new tales of alleged looters or shooters
