Recording in the Mall

I went to the Maplewood mall to record today. I got most of the sounds I wanted, but I was cut short. As I was recording a gumball machine, 5 cops came up to me and asked me what I was doing. As I was explaining to them, another 10 men walked around the corner. During the course of the next few minutes, people just kept pouring into the area and surrounding me. Finally, they told me I had to stop. I think they thought my H4n was a handgun or something. haha
