Gang rapists being executed is fine by me. I have no comment or opinion on mc clubs in countries other than the US.
Tell me how many instances of that you can find in the US. It has happened, and will happen again at some point, but a hundred examples? Nope.
If I perform an international search for cops convicted of murder or drug dealing I will find examples all across the globe. Does that mean every single cop is a drug dealer or murderer? By your logic...yes it absolutely does.
