Not for everyday wear, but I'd love to see about 500 of these being worn around the Capitol building while some of our favorite bills are being discussed. Imagine the line at the special entrance for CHL holders.
I tend not paste bumper stickers on my truck, or wear shirts, that indicate I have a gun -- I would like it to be a surprise to anyone wishing me harm -- but there is room for bolder statements, particularly in the right settings.
BTW, I would like to see a citation to any self-defense shooting (or any shooting whatsoever) in the state of Texas that was prosecuted or civilly litigated wherein a bumper sticker or shirt statement was part of the evidence... References to Massad Ayoob don't count. He comes from a jurisdiction that might as well be on a separate planet, tends to make his writing a bit gloomy at times.
