I honestly don't think that there has been much change in opinion. But if you are around the same people every day, those individuals may become more accepting/desensitized to the issue. For instance, I carried at my local Starbucks in Kirkland quite often. I could always account on someone calling the police and a band of four or more police showing up and checking the situation out. To their credit, I was never approached or harrassed. They simply showed up, grabbed a coffee, stayed a few minutes then bolted. After time, the Starbucks employees actually started talking to me and recognizing me as someone they could have a casual conversation with. Many even asked me about why I carry. My response is never to say simply reply "personal protection" when asked. I respond with a question. I say "Are you aware that the police have absolutely no duty to defend or otherwise help you as an individual?" That starts an actual conversation and usually the response is "that can't be true". In which case I get to educate the individual on landmark "no-duty to protect" cases. I then get to tell them of instances where this no-duty was applied in the state.
That was before my recent arrest. Now that my case is dismissed, and I'm getting my firearm back, I have come back to Starbucks tonight where I'm posting this message from. I realized in the three months it has taken my case to get dismissed, I have a whole new set of employees here. I'm hoping I don't have to go through the same silent treatment again.
