That might be the liberal position on average, but if you have a social circle that’s lefter than average, as in many metro areas, you’ll occasionally hear a desire for outright abolition of police. Not even a simple local constabulary walking the beat, as there is a meme going around that such law enforcement came out of gangs that hunted down fugitive slaves and is inherently tainted. (Nevermind the existence of such police in countries around the world that never had race-based chattel slavery.) Instead, more investment in social services will supposedly remove the need for them entirely.
But of course, whether that position or the number of people who hold it, has any real influence on gun sales is doubtful and the GP may have been a bait post.
