So, in a nutshell:
If the situation justifies the use of deadly force, you are safe to draw.
If the situation does not justify the use of deadly force, you may not be safe to draw.
If you've got no intention of shooting, you've got no business drawing. That does not mean that if you draw you must shoot, just that if you draw you darn well better be "ready, willing, & able" to shoot.
Bingo. (for most states)
.....just that if you draw you darn well better be "ready, willing, able & legal
" to shoot.
