In this situation, Jimmy couldn't drag Julia to their surveillance van, so he had to stand guard with his gun. He wasn't sure if there were other hidden gunmen around, so he had to hold his ground like this.
Fortunately, 911 was quite efficient, and with the large number of NYPD officers, the sound of sirens soon filled the air as patrol officers returned to clean up.
Every police car came equipped with a first-aid kit. After Jimmy showed his identification, the patrol officers came over to assist him in providing temporary hemorrhage control for Julia. After a few minutes, a fire truck arrived, and the paramedics took over Julia and Jones.
Jones was also lucky; though he had been shot, the bullet hadn't claimed his life. The most dangerous one hit his face, passing through the cheek without hitting his brain, which was fortunate, though his face would certainly be scarred.
