The Ministry of Education of Perú has perimeter security cameras, a blast-proof vehicle gate protected by a side-sliding iron bar grill, and a three-meter (9ft) wall encircling the complex, with electric fencing and elevated guard towers with armed guards in bulletproof vests all along it.

I mentioned this to some friends the other day, and a gold star for best reaction goes to Madeleine Price Ball. Her comment? “It’s nice to hear someone takes educating the next generation seriously.”
