I'm not opposed to enforcing laws at all. My point was that abortion is not an issue that can be solved by arresting people and throwing them in jail.
That part is true. Just because we have laws (abortion laws, highway laws, etc) doesn't mean people will not break them.
True, and of course sometimes the time, effort, and money necessary to enforce the law is often greater than the benefits.
But in this case, I would argue that first of all, it's not a law enforcement issue, or one that the police can do anything to fix (that was the point of my first post on this thread). It's an education and a family issue; ensuring that everyone has an opportunity to get ahead in life from birth right on through adulthood, due to good parenting and excellent schools. That's ultimately the solution to abortion, not arresting people and putting them in jail, which will have very little benefit compared to the cost and may in fact even be detrimental in and of itself in many cases.
