My quick response:
Bob Schieffer compared "taking on the gun lobby [NRA]" to laudable, hard-fought historical battles in the United States's past, such as the passage of civil rights legislation, the successful hunt of Osama Bin Laden, and battling Nazis. In making these comparisons, he shows his obvious bias, likening the NRA and its members to racists, terrorists, and Nazis. Bob Schieffer owes NRA members like me, a law-abiding, former Naval Officer and fighter pilot, businessman, husband, and father, an apology for his flawed and biased analogy, and he should be reprimanded for presenting such an unbalanced diatribe as credible journalism. I expect more from CBS news.
If it jams, force it. If it breaks, it needed replacing anyway.
