How long will it take a backhoe to get through it?

In the case of the HA, their primary goal was to slow down,
not necessarily stop the cops. The large concrete blocks
in front of the concrete wall keep a backhoe at a significant
distance too. All in all, the design looks like a typical
US embassy or consulate.
