Common sense prevails.

The Pennsylvania school district superintendent who discussed arming teachers with rocks last week is now stepping up school security. The security will be armed with guns.

Blue Mountain School District superintendent David Helsel commented last week that the district would be arming teachers with a 5-gallon bucket of landscaping stones in each classroom. The quotes immediately brought criticism — and ridicule — over the practicality of students and teachers being faced with having to hurl rocks at an armed attacker.

The school district announced on Sunday that beginning this week there will be increased security at schools due to the media attention the comments received.
