This is generally how I am hearing it related to the real world

Person A picks up a knife and points it at person B asking for money, the Cops come on person B plead and arrests person A

Person A try to to whip up a storm on the local news paper that Cops are arresting people for holding a knife, bla bla bla, unfair, human rights, etc.

It doesn't change the fact that you try to use something to rob others, and claim it was a problem with the way you hold your knife.
