Every mass murder in the last 20 years occurred or started in a “gun free” zone. IMNSHO: Any employer/retailer/government agency that establishes a “gun free” zone should assume all liability for the person's safety from the last place they could have carried.
I don’t disagree, I just wonder how the nasty entanglement of cross-relevant rights will end up playing out.
