What George Zimmerman Was Doing Outside Florida Gun Shop

— -- Former neighborhood watchman George Zimmerman is back on patrol -- and this time it's at a gun store.

Police found Zimmerman sitting in his dark colored truck outside of Pompano Pat's, a store that sells firearms and motorcycles, just after midnight on Sunday, according to a DeLand, Florida police report.

Zimmerman, who police said was "very cooperative," explained to the responding officer that he had the owner's permission to be on the property and was patrolling it since there had been a recent burglary.

He provided officers with a phone number for Pat Johnson, the owner of the business who is also running for mayor in DeLand. Officers were unable to make contact with Johnson.

According to the report, Zimmerman told officers that Johnson had asked him to leave his dog inside the business, however Zimmerman decided he and his dog would wait in the parking lot.

He also told officers that "he was going to be around the business at night for an indeterminate amount of time," the report said.

Sam Porter, an employee of Pompano Pat's, told ABC News today that Zimmerman is not an employee and is not being paid to patrol the business.”

“George is a really nice guy and really tries to help folks out," Porter said. "I felt he was trying to do something nice."

Pompano Pat's had offered Zimmerman a free gun after he was acquitted of murder last year.

Zimmerman maintained self defense when he shot and killed an unarmed teenager, Trayvon Martin, in Sanford, Florida on Feb. 26, 2012.
