Very concerning, to say the least. It has to be a series of inside jobs. I especially want to know if there's a pattern in who those arms are going to.
Have I missed past coverage? I haven't heard about it before this.
*edit - Based on the article, a bunch of these are probably incompetence or complacency about handling weapons in the field, but with that many missing or stolen guns I still have to wonder if there are patterns in where they're going.
