Either way, if'n I have to use my "bling" Glock to defend myself, after it's impounded pending investigation, I'm sure having a Predator symbol, or Biohazard emblem, will be exploited by an anti-gun prosecutor, that would love to paint me as an NRA, CCW, Tea-Party, Rush Limabaugh, Glenn Beck, Sarah Palin, Ronald Reagan, Bible totin' evil Conservative, who probably even admires Dick Ch
eney and Rumsfeld.
