Can you tell me how the US government uses surveillance technologies for homeland security?
<|assistant|>
The US government uses surveillance technologies such as satellites, radar, biometrics, digital communications intercepts, and facial recognition for homeland security. These technologies are used to detect and identify potential threats and help monitor suspicious activity. They also aid in search and rescue operations and protect military and civilian personnel on US soil.
