Convicted pedophiles from the U.S.should be barred from crossing the border, they are walking over in hoards, ask any border patrol agent working the counter at the San Ysidro crossing, when they scan their id's, their records come up. Americans are buying or just taking poor Mexican street children and renting, selling and filming them for sex acts. Ask the vendors and the taxi drivers in the Tijuana border area. These children are not returned to their parents. They are used until they are dead. Please do something, at least can't anyone investigate this!!
