*On the evening of June 9, 1990 — a month before Patton turned 18 — Patton and a Klan leader took a semi-automatic TEC-9 pistol and drove to a synagogue in a Nashville suburb. With Patton at the wheel, the Ku Klux Klan member fired onto the synagogue, destroying a street-facing window and spraying bullets and shattered glass near the building’s administrative offices, which were next to that of the congregation’s rabbi. No one was struck or killed in the shooting. Afterward, Patton hid on the grounds of a white supremacist paramilitary training camp under construction before fleeing the state with the help of a second Klan member."

Paragraph 6 in the linked article.

The charges seem comparatively light, even for the adults, for an act of terrorism and conspiracy to murder (although fortunately not succeeding).

From the paragraph before your quote:

It's in the article. He was the driver.
