You may recall the news flap that occurred a couple months ago when someone scaled the White House fence and penetrated all the way to the East Room before he was snared. This would not be quite so likely in Lima, where asalto (assault) police with automatic weapons guard the Palacio de Gobierno along with badged security personnel in suits.
The first time I was in Lima, there was a demonstration expected. Just to make sure that it wouldn’t spill over into any sensitive areas, large groups of riot police with shields were stationed all around the Plaza de Armas.
South America has had a history of violence against government forces, culminating in the hanging of President Gualberto Villaroel, who in July 1946 was dragged from the presidential palace in La Paz, Bolivia, and hanged from a lamppost on the main square—which is still there and which is grimly shown to tourists.
Did I feel safe in Lima? Yes, as long as I followed the orders of the police about standing too close to the main gate.
