It's simple economics.
Given the small number of occurrences and the large expense, it's completely unfeasible to pay for a police officer to sit in every elementary school all week long. If such a plan was implemented, it would result in a significant increase in taxes to justify the staffing increases. People might (big might) be willing to deal with that today, but in six months or a year when Newtown is another place "where something happened once", they won't.
On the law enforcement side, such a plan has recruiting problems, too. I don't think you're going to find a lot of guys who are going to want to do it week in and week out. It's definitely not what I signed up for, and I can do a whole lot more good the vast majority of time on the street. That means you end up with one of two types of officers in the schools: retired-on-duty folks or new inexperienced folks. Both are better than nothing, but neither are ideal.
