90% of the children at the border are unaccompanied. 33% of unaccompanied children are recruited by gang members.

The other 10% are separated and the alleged parents are interviewed for the purpose of finding out if they are who they say they are.
It is done for the protection of the children. There are people working for the cartel pretending to be the parents of children that they intend to traffick and exploit.

Contrary to media reports & lies these children are being cared for and have play grounds for them as well.
