Why not just make a compromise/deal - 10 day waiting period agreed-upon and a unanimous vote would be needed in the future to do anything else in the way of gun reform?
The Clinton era "Assault Weapons Ban" had a sunset clause in it that stated that after a 10 year period if there was no measurable drop in gun violence then the "ban" would be allowed to expire. Well.......there was no measurable drop in gun violence (despite what you hear on TV) so that "ban" was allowed to expire. That was a compromise with the left that failed and we all knew it would. Only a fool would want to give away more freedoms knowing it will fail again just like the last time we had waiting periods.
Every shooting is a reason to try and grab more of your freedoms. They know what ever they put in place wont work, but they still manage to convince uneducated souls that it will. Oh and its all for the good of the children...........the same children that escaped the womb before they could abort them.
