We can't shoot our way out of the gun problem...

After the disruptive mess that was Act 10 and the funding cuts to our schools, the attempted voter suppression in his unconstitutional Voter ID law, and now the loss of millions due to his incompetent management of WEDC, I thought the Governor Walker couldn't do much more damage.  Boy was I wrong: 


On Wednesday Gov.Walker said that arming school officials should be "part of the discussion."  Well maybe it should, as in: "That's a bad idea! end of discussion."

Let's look at the facts: even counting the recent tragedies in Connecticut and elsewhere, we need to remember that schools are the safest place for kids in this country, safer than homes and safer than anyplace else kids are likely to be found.  And not by a little, by a lot.  The first principle of change is: don't mess up what you've got!  
Can we anticipate the effects of guns in schools?  First question: will armed teachers have an impact on reducing events like last Friday's?  30 years of experience says no:  Of the 62 mass shootings in the US in the last 30 years, not one was stopped by an armed civilian.  In a few cases the shooter was apprehended by an armed civilian, after they stopped shooting; but in a similar number of cases the armed civilian ended up dead or severely injured.  Based on that real experience it is probable that an armed school staff would have a negligible small impact on shooting rampages.  Consider, the one person involved in the Sandy Hook rampage who had an arsenal of weapons for self protection, became the first victim.
And what about the collateral damage?  Every year in the US there are about 650 accidental shooting deaths and 15000 injuries.  5 children are shot accidentally every day.   If you extrapolate that rate per gun into 4 guns per school you end up with an expected 31 accidental shootings per year in schools.  And that is just accidents, it doesn't count the all to frequent incidents of "He had something in his hand, I thought it was a gun" - something that happens regularly even with highly trained police; or situations where an emotionally distressed or disturbed person creates a confrontation that has the potential to turn deadly in the presence of a gun.  And don't forget, even police officers only hit their intended targets about 1 in 5 shots.
School can be a difficult place, with young men and women going through difficult changes and situations for which they are as yet poorly emotionally and socially prepared.  Indeed, 4000 teens are sufficiently emotionally distraught to commit suicide each year, introducing deadly weapons into this environment is destined to make schools a more dangerous place.  
I could go on, but the youtube video is worth a million words:  Here a police officer accidentally shoots himself in front of a class room full of students.  Ironically while lecturing about gun safety.
In short, we can't shoot our way out of our gun crime problem, and suggestions that we can ignore reality.
