I agree. In Washington State (a shall issue state), 9.8% of non-felon adults have a concealed carry permit. Plus I would estimate that there are a lot of folks who don't bother to get a permit still carry.
I went to a "Bite of Seattle" festival in downtown Seattle 20 years ago where it was very crowded. Someone thought it would be funny to light a loud firecracker and when it went off, I saw a whole lot of hands reflexively reaching for their waistbands. Seattle is strapped.
Today, they'd be reaching for their crayons and play dough.
