A couple of years ago I caught a plane to Heathrow Airport, London, after conducting an audit in the US. I collected my luggage from baggage claim and waited in line like everyone else for the hotel bus.

I noticed they weren't talking to one another, had no luggage and the man was holding the woman and children's passports and travel documents. I was convinced they were being trafficked but I didn't know what to do. Should I ring the police, contact airport security or tell the bus driver? However, doubt crept in. I could be mistaken. They could know each other. In the end,I got on the bus and did nothing.
