Yep, what Mobuck said.
I'm a long time LEO, currently working in a school-house as a resource officer. I spend a lot of time looking at people's belt-lines as part of my normal scanning. I'm amazed at the crap that people carry on their waist-line. Cell phones, pagers (yeah, some folks still carry pagers), leather, plastic, metallic, it's all there. I may not know what their faces look like, but I can tell you what color belt they're wearing.
