I'd like to see states pass laws that shield employers from liability for firearm related issues when licensed CCW holders carry on the job. As you point out an employer might not personally object to having someone carry on the job if there wasn't major financial risk associated with it (insurance premiums, lawsuits etc). By removing the employer liability for it you'd eliminate the financial obstacle to carrying on the job. The law could have a requirement that employees have attended basic handgun training like the
NRA Basic pistol course. That would placate some of the objections you might get in constitutional carry states where anti gunners would state "any untrained bozo could come in with a gun" (we all know the reality though - any untrained bozo could always come in with a gun regardless of laws or jurisdiction - looking at you Illinois). Arizona has tended to be a pretty forward thinking state where handgun laws are concerned - how about it Arizona?
