Progressive government in action: Migrant beats cop, set free, shoplifts

There was a time when slugging a cop would get you bumps on your head — along with maybe three-to-five at Dannemora state prison, up on the Canadian border.

But times change.

There are (at least) two lessons here:

When a border-busting teen-aged thug charged with felony assault on police officers walks free without bail, only to reappear just weeks later as part of an organized shoplifting crew, something truly is bent.
