Another dispatch from reporter Nina Lakhani in Tijuana:

Despite the large numbers of people from Central America waiting at the US border in Tijuana, Mexico, the scene is remarkably ordered and cooperative.

The people are initially strangers to each other, brought together in an alien location.

It’s not risk-free at the shelters and while lining up at the border, but the atmosphere is largely one of stoicism and mutual assistance. As well as an informal numbered ticketing system for the queue, devised by migrants themselves, those waiting put themselves forward as volunteers to manage the list of names seeking asylum. On Friday morning, a Honduran man was looking after the list and he was ready to hand over to someone else when his turn came to get ready to cross the border.

So, far from a Lord of the Flies-type breakdown in social order, as you might expect if you only listened to Donald Trump’s name-calling and aspersion-casting, these would-be immigrants are more inclined to help one another as they wait and hope to escape from dire straits.
