A Florida gun store owner caused controversy upon his announcement that Muslims are not welcome in his store. 

The owner Andy Hallinan made a video explaining his decision. Hallinan claimed that last week's deadly attack at a naval base in Chattanooga was the breaking point.

"I believe that the vast majority of Muslims are not out to kill us. But unfortunately, the Koran, the way it's written commands them to", Hallinan said. 

Some store customers supported his decision. One employee quit shortly after the video was posted. 

Hallinan said, "Unfortunately I had to offend everyone to get my message across."
