Who cares. they were apprehended and sent back.
We can't possibly stop every murder from happening either, but that does not mean that we have a murder-permissive society.
"It's estimated that over a million are coming in every year illegally."
"Estimated"?
Estimated by whom?
By the same people who, in spite of the very real, very verifiable statistics on the number if people who are stopped from entering the country illegally each year claim that we have "open borders"?
I guess we have no law enforcement because there are millions of crimes every year.
I guess we have an anything-goes society because you can buy drugs in every city and town in America.
I guess that since we can't stop all crime, we may as well just throw our hands up and give up.
"It's not that difficult to get over the border."
Oh yeah?
By your own unsubstantiated, alarmist estimates, 50% who try to do it get caught.
I don't call that "easy".
