This legislation is dangerous.  As we have seen time and time again across the United States signs and laws do nothing to stop someone intent on doing harm to others.  The only people who would obey this are those that are law abiding citizens of whome you needn't be afraid.  By taking this step you will simply be making more places into "defenseless victim zones",  places where evil can be perpetrated undeterred until law enforcement arrives with their guns to stop it.  I urge you to talk to your sheriffs as most of them have shown that they understand and know what I have said to be true.  Speak to street level officers and they will tell you the same thing,  that this ban won't stop bad guys but could prevent prevent good people from being able defend themselves. Stop this lunacy before it begins.
