Given the late and recent tragedies the need arises to render a firearm useless in certain areas. Here is a solution
to control where these weapons can be used and where they cannot. A wireless locking mechanism attached to each firearm should lock itself when the weapon is in the proximity of a school or other crowded location. it is the responsibility of each state to have each registered owner to take their weapon to an approved center and have it installed. It is a win-win. The manufacturers can continue their production, the gun enthusiasts can continue shooting at the range, and the kids and concert goers will be safe if this gets implemented.
This design is dedicated to the memory of the ones who took the pain and gave their lives so others could live.
