They want the crime.
If you defend yourself they arrest you instead.
They would rather murder gun owners for daring to own guns than do anything about criminal thugs.
Remember, it’s “raycis” to hold gang members accountable for their crimes, it is “white supremacy” to believe you shouldn’t be robbed.
Stopping crime is a trivial exercise.
Arrest the criminals and throw them in jail for a long time.
It works.
Any other approach is doomed to failure.
