1) I'm well aware on what the picture showed.
2) The article was on private prison owners meeting with Trump, not the cost of housing an inmate....be they here illegally or otherwise.
3) You should know by now that we don't get to pick and choose what our taxes go towards as individuals.  I think a border wall will be a waste of money (especially when your deity said that Mexico would pay for it), but I don't get to sit here and say, "you pay for it" if the folks in power decide to waste money on it.
4) I was unaware that we, as American citizens, had some sort of new "zero tolerance" policy.  When was that passed....or is that your lame way of telling me that I'm not a true American?
5) You can bill these other countries until the cows come home.  They will be under no obligation to pay.  Do you honestly expect other countries to stop letting people leave?  That can also go both ways.  You're ignorant if you don't think Americans ever get jailed overseas.  Should they bill us too?
