Top administration officials have directed 21,000 border patrol officers to retreat whenever illegal immigrants throw rocks at them, and to avoid getting in front of foreign drug-smugglers’ vehicles as they head north with their drug cargoes.

“Agents shall not discharge firearms in response to thrown or hurled projectiles… agents should obtain a tactical advantage in these situations, such as seeking cover or distancing themselves,” said the instructions, issued Mar. 7, under the signature of Michael Fisher, chief of U.S. Border Patrol.

Agents were also directed to keep their weapons holstered when drug smugglers drive by.
