Danger of Harm
You can commit a deadly conduct offense in Texas whenever you engage in any type of conduct that you know, or should know, will place someone else at risk of suffering serious bodily injury. For example, if you point a gun at someone else, you can be charged with deadly conduct even if you never fire the weapon or never intend to fire it. It's enough that you intentionally brandish the weapon and know, or should know, that such an act poses a danger to someone else.
