Huh?
I will take responsibility for the breakdown in understanding.
Criminal crosses border and kills an American citizen.
If not allowed to enter the US they would not have been in the US to kill the person.
If my neighbor never goes to Nigeria then he won’t be there to be killed for being a Christian by the Nigerians.
Jose Inez Garcia-Zarate, the previously deported and re-entered man who shot and killed Kate Steinle was not supposed to be in San Francisco. He was a foreigner in our country.
“I chose to re-enter the country in San Francisco because it is a sanctuary city and I knew nothing would happen to me there.”
Thus, with proper border enforcement, Kate Steinle and her father that night on Pier 14 would not have been in danger because the alien would not have been in the US.
