So, armed robbery isn't a violent crime because they were only pretending that they would kill me? I know that the weapon in this case was a BB gun, but someone who uses the threat of violence to get money isn't in the same category as a common thief. If someone pulled a BB gun on me during a robbery, I would attempt to shoot them to save my own life.
1> I have no idea that the BB gun isn't a real gun.
2> Regardless of the criminal's words, I have no knowledge of their real intentions or capabilities beyond what they present to me.
3> I can't take their word that they only want my money, since they've already shown (by threatening my life) that they value life below property.
