America's Most Ungrammatical

The Associated Press reports that convicted shoplifters outside an Alabama Wal-Mart have been sentenced to stand outside the store holding signs that say: "I am a thief, I stole from Wal-Mart."

Sigh.

Any of the following would have been correct:

I am a thief; I stole from Wal-Mart.
I am a thief. I stole from Wal-Mart.
I am a thief who stole from Wal-Mart.
I am a thief -- I stole from Wal-Mart.
I stole from Wal-Mart.

There is justice in grammar. But apparently, there is no grammar in justice.
