Disconnect battery when parked?

Lot's of controversy on whether it's a good idea or not to have a kill switch or disconnect switch etc. We have all heard the crazy stories where we ask "how could that happen ". So for me I believe the cost and inconvenience of turning on / off the switch is small compared to losing my cherished old mopar. Just like I have it insured in case something stupid happens. Better to error on the side of caution. You may disagree.
