Basically, non-gun owners are riding the safety net created by gun owners. They have no means of self defense, they are riding the safety net of neighbors with guns. And whining to tax us with police protection. All the while, their homes are protected with our guns and/or the perception that they MAY have a gun in the home whether they do or not.
There is nothing in the bill of rights that guarantees police protection, only self defense.
If one wants to forgo the responsibility of self protection, fine, but we need to assign some more police to protect your defenseless selves so we need a surcharge to afford this.
5% usage tax, dedicated to policing. If it saves one life it is worth it.
