A noble cause but does nothing about the patchwork of city laws within a state that vary wildly from community to community. What is needed is to work at the state level for preemption laws.
What is needed is for the constitution to be enforced. That should supersede the patchwork of laws about knives. Make no mistake; knife law enforcement is not to make streets safer but to make a larger pool of felons who are forbidden from owning guns. Most of these knife laws are there as back door gun control.
