WATCH: Amazon Driver Allegedly Assaulting 71-Year-Old at California Gas Station

A disturbing surveillance video from a California gas station has gone viral after an attorney released footage showing an Amazon delivery driver allegedly attacking a 71-year-old man during what reportedly began as a dispute over a parking spot.

Attorney Tony Buzbee posted the video Saturday and said the incident occurred at an ARCO gas station in Elk Grove, California, on March 30.

According to Buzbee, his client is a 71-year-old auditor who works with agricultural and animal production facilities. The man reportedly stopped at the gas station during his workday to use the restroom and buy a soft drink.

What happened next was anything but routine.

Buzbee said the delivery driver apparently believed the older man had taken his parking space and became aggressive.

The surveillance footage shows the driver confronting the senior citizen inside the store and threatening him before the situation turns violent.

“I’m gonna beat you a**, n****!” the driver can be heard saying in the footage.

Moments later, the driver appears to strike the 71-year-old from behind, hitting him in the back of the head and sending him crashing to the floor.

Gas station employees look on in apparent shock as the driver then walks away.

It is the kind of video that leaves viewers wondering how a parking-space dispute could possibly escalate into an alleged felony assault on an elderly man.

According to Buzbee, his client continues to receive treatment for neck pain and a concussion following the attack.

The attorney also said the driver was arrested and charged with felony battery and elder abuse, among other charges.

Those allegations will ultimately have to be resolved through the criminal justice system, and the accused driver is entitled to the presumption of innocence.

But the civil side of the case is now drawing plenty of attention as well.

Buzbee said his firm has filed a lawsuit against Amazon in Sacramento County Superior Court. He also alleged that the driver had a prior history of violence and accused Amazon of inadequate hiring practices.

That claim could become a major issue in the lawsuit.

If a company places drivers on public roads and sends them to homes and businesses across the country, the obvious expectation is that those employees or contractors have been screened appropriately and can interact safely with the public.

Nobody expects every hiring system to predict every bad act. Human beings are not software updates. But if there were prior warning signs involving violence, then lawyers are going to ask whether those warnings were known, whether they should have been known, and whether the company did enough before putting the driver behind the wheel.

That is where this case could become much bigger than one ugly confrontation at a gas station.

The video itself is already generating outrage because of how sudden and seemingly unnecessary the attack appears.

A parking disagreement is annoying. It is not a license to threaten someone, follow him into a store, or allegedly sucker-punch a 71-year-old man from behind.

Buzbee said his client was simply trying to get through his workday.

Instead, he ended up injured, treated for a concussion and neck pain, and involved in both a criminal case and civil litigation.

The lawsuit against Amazon will now test whether the company can be held responsible for the alleged conduct and whether its hiring and screening procedures played any role in what happened.

For now, the surveillance footage has already done one thing very effectively: it showed the public just how quickly a petty dispute can turn into something serious.

A parking space is not worth a concussion.

Apparently that lesson still needs repeating.
