I agree. But I was never much of a proponent of open carry laws generally. This essay about volunteer security in Ferguson makes a good case for why open carry laws are important, even if you prefer to CCW normally.
1) The Second Amendment reads "shall not be infringed".
Do we really need another reason?
2) Concealed carriers shouldn't be arrested or hassled for "showing" or "printing" or other silliness.
3) Sometimes open carry is better; when meeting as an unorganized militia, for example.
