Where there is a caution sign, it means someone has done something stupid before. Same thing for public service announcements. Same reason why many of the school districts in the Washington DC region have been holding parents-only meetings regarding human sex trafficking.

A recent trip on the train system found me watching a PSA on you guessed it...HUMAN SMUGGLING = HUMAN TRAFFICKING. If you see something, say something.

A quick Google search will confirm this.

As I rode the rail, I noticed several sets of "unusual families." It is hard to put my finger on, but things like a 17 year old girl looking after 7 yo boy of central American descent. Or white parents with bi-racial/mixed kids. Yes, I am aware this does happen, but I've developed a sense for "creeps", and there were some individuals that ticked my pedometer.

I know I'm being a little over-sensitive on this. But I confirmed this though - the US rail system is a perfect infrastructure for transporting humans. Especially ones that are "trained".

See what turns up here.
