It is my understanding that there used to be a "safe harbor" provision in Tennessee gun law that basically kept you from being subject to criminal charges if you employed justified deadly force with your handgun in a location where that handgun should not have been carried to begin with.
Example: You're eating at Logan's Roadhouse and someone comes in and starts shooting the place up. You shouldn't have your own handgun with you since they serve alcohol for on-site consumption, but you smuggled it in anyway. You use your handgun to take down the killer, saving not only your own life but the lives of many others.
The law used to be such that you would not be charged with the misdemeanor offense of carrying where it was prohibited.
BUT...
It was the opinion of John Harris, esq. that the recent amendment to the Tennessee Code Annotated that more or less granted us the "must not retreat" Castle Doctrine sort of provision that we no longer have that assurance.
The new TCA statutes assert that you can only employ deadly force so long as you are not in the commission of a crime!
Since carrying where prohibited is a crime, would you still be granted safe harbor for defending yourself? Or would the Court bury you beneath the jailhouse because you were illegally carrying at that moment?
See, this is why TCA needs a serious overhaul in regard to gun laws.
