The latest US school shooting to make headlines, in Maryland,
is a story featuring a School Resource Officer or SRO.
While the shooting investigation is still underway,
it is stated that the shooter had a confrontation with
the School Resource Officer.
The shooter is dead; when I heard updates,
it was still being determined if the fatal shot
was self-inflicted or delivered by the SRO defending the school.

When the high school in Chardon, Ohio, was targeted by a shooter
six years ago,
there was no SRO there;
the shooter was famously confronted by Frank Hall,
who coached football, taught (math, was it?), and presided at study hall.

Between then and now, Frank Hall has been an outspoken advocate
for SROs in schools,
contradicting Trump's suggestion of arming schoolteachers.

Does the tragedy in Maryland today
prove or disprove Frank Hall's opinion?
