It is still amazing that these type of demands are up and running in the 21st Century. Missouri, a state that lately has been getting beaten over and over on the news lately and has been accused of having the weakest Shall-Issue CWP laws in , dropped the letter of reference crap in 2004. And yes, the LEO Letter was to keep minorities from getting permits, pretty much as a poll tax or literacy test was designed to keep them from voting.
And what really makes this more insulting is that the Sheriff of Imperial County should know better.
Then again, Gun Control is about Control and that is too tasty for anybody from any race yearning for power to pass up.
