From an educator's pov. There are, of course, pros and cons to this. But logically speaking, why not have an extra layer of protection for our kids?

On a political level, these things get tricky because of the "image" this perpetuates. Tax payers (especially in more well off areas) don't necessarily agree with armed guards and/metal protectors in their schools because they won't "appear safe or affluent".

School boards officials are ran by the district they represent. These school board meetings get ugly and last all night when these issues arise.

It appears that some people feel their money spent should equal safe schools (without the need of armed guards/police seen urban schools).
