Being mentally prepared to use your weapon can be as important as having your weapon prepared for use. Assuming you will never use your weapon for self defense and further assuming you will probably have time to charge your weapon prior to its use is...well...not being mentally prepared to use deadly force. While it's still a free country and you are free to think how you will, and free to carry as the law allows, just know that you already have two strikes against your survival "in the unlikely event" of a deadly force encounter. Your life, your risks.
