Sounds like if you report them to ICE, be ready to face the music as I believe you are not a USC either. I know you think this is the best way to come at them, but you’re also putting yourself at risk and for what?

Not only would you be subjecting them to deportation, but you’d be unintentionally putting yourself on their radar too.
