Why not raising the level of fear in people by showing Walmart bloody scenes?
We are now so used to shootings news that we don't take it seriously anymore. After a few days, we forget about it. I feel if TV media starts showing bloody scenes of shootings with bullets hitting heads and bodies, then people get so fearful that they start protesting to force politicians to do something about the issue. Showing those scenes in the public would also embarrass the nation which might trigger some actions.
