Polls, not pole - mandating training is an interesting issue. I do think people benefit in TX from the information about discretion in using force.
Perhaps, when you get your CHL - they should give you a CD with the info.
Good training is more than basic gun handling, it includes how and when to use lethal force. It also includes scenario training which is more than gun handling.
Mandating it is a different story. I do like people who get CHLs to have exposure to the laws and conflict resolution.
