It is time to act! We have suffered enough with mass shootings in our schools since the fateful day of Columbine. The time has come to turn the tides on the attackers. Let us as a nation, begin being proactive rather than reactive. I petition for our government to install bulletproof doors for every classroom in our K-12 school systems. Everybody will say, "It will be far too expensive". The fact of the matter is, that in truth, it is not far too expensive! The Charleston County School System in South Carolina has already begun steps to install these doors in three pilot schools. These doors can withstand shots from an AR-15. A single door cost $4,000 dollars equating to 4 cents per student a day. That is $7.20 per student a year. Ask yourself, " Is 7 dollars worth a life?
