Students march, again

When students marched to oppose anti-immigration policies today in downtown LA, they dedicated the march to Anthony Soltero. 14-year-old Soltero killed himself, his family says, because school administrators threatened him with jail for participating in a student walkout. His funeral was this morning.
Meanwhile, today's march has sparked a math crisis in some of the city's best local newsrooms.

We know for sure that there were at least two blogger-photographers there — Dave Bullock and Don Garza. This time, the photo we've borrowed is Don's.
