Hey! Castro is a hero of the OWS. In case some too young to remember.. here is what "To the wall!" means, just trying to help get their message out.
The Infamous Firing Squad -- Thousands of Cubans have died in front of Castro's infamous firing squad. There was no discrimination, as far as the firing squad was concerned. Young and old, black and white, rich and poor were sent to 'el paredón' (the wall). Many of those who helped Castro gain power, like Comandantes Ernesto Sori Marin and William Morgan, an American, were among the thousands who were shot. [my emphasis]
