What would it cost to put a teacher in every gun store?

[Coyotl]

3. In the last two years, we have enough unemployed educators to place four of them in each gun shop!

It is intelligent sarcasm. In the context of proposing an armed guard in every school. It also points to the absurdity of placing gunman in schools, while at the same tiome sounding like a good idea itself even if absurd. Consider also how the stats point to the fact that in the last two years alone, we have enough unemployed educators to place about four of them in every gun store!
