A very interesting point of the data analysis is on page 11 the most common security measure used where potential attacks were averted was “Security Officers or Police Officer at/in school”. It is not surprising to me but in the current climate where there is a push to remove police from school in the capacity of SRO or SLO this call for action should be re-examined.
