Uh, yeah.  I seriously question whether even 50% of users here have anything that resembles a conscience.   At least it's a safe bet that you shouldn't appeal to conscience here.  Anyway.  Wrongdoers tend to get caught eventually,  and especially money launderers.  Just don't do it.  Do things the right way and you're right,  you won't have to worry about the cops banging on your door,  or the tax man.  Speaking of which,  Mr taxman really should leave bitcoin alone.  He gets more than his fair share.
