From the dissent:
“[A] typical citizen fearing for his personal safety—by definition—cannot distinguish himself from the mainstream.” Ibid. (emphasis deleted; internal quotation marks and alterations omitted). As a result, ordinary, “law-abiding, responsible citizens,” District of Columbia v. Heller, 554 U. S. 570, 635 (2008), may not obtain a permit for concealed carry of a firearm in public spaces.
So is the author admitting that everyone fears for their safety in San Diego?
How does Heller sustain this finding?
I don't read Thomas's dissent for that proposition at all.
