I believe I read in the article that the Police chief said they were "very secure". I'm sure there are probably other things they could do, but being a local business, I have to wonder about economic feasibility. A vault would be an incredible economic burden, and I'm not sure it would make sense for a small shop to take on such a cost. Honestly it may just be more economically smart to just deal with the break in's and have the insurance cover the cost. I also think it's perfectly acceptable for someone to be upset when something they've worked incredibly hard for is destroyed by criminals. Just my opinion though.
