There have been numerous suggestions for an armed security guard being in school buildings. That made me curious enough to run some numbers.
There are a little more than 130k school buildings for k-12 in the US. If the pay and benefits for each guard is 75k the annual cost is 9.75 billion dollars each year. The total cost would have to also include the expense of ongoing training.
Since Columbine there has been 169 people killed in mass shootings in schools. There have been 14 mass shootings in schools since that time. A mass shooting defined as 4 or more deaths. Lets include Columbine and make it 15 shootings in call it 23 years. That is .65 mass killings in schools per year. The draw odds for each school building to have a mass killing each year is one in 200k, give or take. So, on average, each school building must wait for 200k years for their mass shooting.
So every guard in every building is in essence waiting for Godot.
If we assume that these armed guards entirely stop mass shootings, the cost is $15 billion dollars for every mass shooting prevented, if the risk is the same going forward.
Some might think that is preferable to other possible solutions. I don't
How many K-12 public schools, districts, and students are there? And how much are we, as a nation, spending on the education?
