The border patrol should have responded to the thrown rocks with rock salt fired from shotguns.
As for the whine about "The US should show some concern for the chil-runs",the PARENTS should have shown respect for them by keeping them at home instead of endangering them by taking them on a long trip to invade a foreign country.
Looks to me like what we need to do is finish the steel slat wall that Trump wants,and electrify the SOB.
