I've not seen a thread regarding the rule changes, but it strikes me that neither I, nor any of you would be flying without our sewing kit. The new TSA rules recognize that the individual is responsible for defending themselves against the small stuff. The same logic would suggest that the citizen has the same responsibility and the federal government should adopt the same logic with regards to our terrestrial pursuits. In other words, the law should embrace the arming of law abiding citizens. Statistically, the threat posed outside of the airport presents itself with greater frequency and with weapons that go beyond scissors and tools. The lawful counterforce should be proportional.
