Well, he's another douchy veteran who "claims he loves guns but wants gun reform," so it's no surprise he's someone lacking in credibility. Anyone who says he loves guns but wants gun reform is a flat-out liar regarding his love for guns, and if the guy is going to so boldly and publicly lie about that, then he has to be doubted when he publicly makes other claims regarding gun-related matters, too.
And I'll say it again. I'm sick of people lending credence to anti-gun sentiments expressed by veterans just because they're veterans. If being a veteran made one an authority on gun rights, then why aren't they highlighting the sentiments of the vast majority of veterans who are fully pro-2A? (rhetorical question) That embarrassing slob can stuff it.
