It's a sad commentary on the state of the Union that requires one to go into the public armed to protect oneself . .
In Colorado, if you strike or attempt to harm a citizen who is over 65 years old, you can (and will) be charged with 3d degree assault on a person at risk, resulting in 90 days to 8 years incarceration.
However, being over that age and preferring to not get knots on the head (or worse) to prove I've been assaulted (or robbed), I choose to carry . . and do much as the man in the news report did . . get a body count . .
And . . If you choose to carry out of self defense, practice, practice, practice . . Don't let two sides of the story happen . . it's almost impossible for the robber's estate to sue for "loss of wages" . . but he can, if he lives . .
