Again, this is the point I'm trying to get across. If things are that bad make a change that will allow the pro's meaning someone more efficient at their job than regular police to be at a much closer proximity than they presently are. Who cares about the cost. I'm quite sure that a community in that much trouble will find a way to fund it.
Who cares about cost? You are a riot! Cost is a significant factor in every community and it is a huge reality issue.
Of course, you can't fund a defense after the fact. Which of the following schools were located in communities that were "in that much trouble"? Of those, which are communities that have enough money to fund the changes needed?
University of Texas at Austin massacre
California State University, Fullerton library massacre
Cleveland Elementary School shooting

Just how do you go about trying to fund improving security for a problem you don't know that you are going to have at some unforeseen time in the future?
