No one wants to spend the money...so we'll continue to see useless smoke and mirror diversionary tactics about school safety. Because honestly, to do it right will cost money...lots of it. That is implementing strictly secured and monitored entrance and exit security access control points manned by multiple armed LEO's and/or Armed Security Guards operating metal detectors and hand held wands.
This would be a massive undertaking, but it is how we secure our society's other valued institutions...like court houses, prisons, etc. This would still be the most expedient way of making schools safer. And I "get it" - the bottom line with guns are they all are ultimately made to do the same thing...put holes in things and kill them.
Just look at human history Mankind (or should I say "Person-kind") has been creating new and inventive ways to kill one another since the beginning of time.
If anyone thinks building a wall is hard try confiscating over 300 million firearms (at least that is the estimated "known" number) doing so would be an even more complicated and expensive task. Bare in mind this would involve violating a lot more than just our 2nd Amendment rights - the 4th, 5th, and 8th Amendments also come to mind but I'm sure there are more...
Meanwhile criminals would still get there filthy mits on illegally obtained guns, while those with evil intentions who still want to make the evening news go about killing in every other way imaginable - which we've seen before done with trucks, bombs, knives, and airplanes.
While the politically divided extremes argue the same tired points and counter-points in their egoistically driven desperate attempt to prove their side "is right" schools are not being kept safe...that is the bottom line.
I think the number one concern at this time should be school safety. I have a lot of friends on both wings of our political bird, and I know many on the left wing will disagree with my assessment/opinion (and that's ok...we're still friends as far as I'm concerned) but the only way to quickly protect our children from guns at this point is going to be with more guns.
It's going to take good men and women with guns who are prepared and ready to get violent to protect our kids from the evil that bad people would inflict upon them. There is no other immediately feasible way that I can think of. I'd be open to suggestions - then we can send them to our political leaders and make something happen.
