The agents state that Silver is driving a red Toyota. The car that appears is a Honda.
OA spots the suspect from at least two floors up, in a stairwell at the courthouse, and calls him by name. The suspect (unsurprisingly) runs. In the foyer, he grabs a police officer's gun (surprisingly easily) and shoots him, three times. The officer's life-threatening injuries are clearly OA's fault. He could have kept quiet and tried to catch up to the suspect. (Does anyone in TV shows ever stop when someone shouts "Police! Stop!"?)
