The warning popup is quite a sight

As part of this monitoring, DHS may acquire, access, retain, intercept, capture, retrieve, record, read, inspect, analyze, audit, copy and disclose any information processed, transmitted, received, communicated, and stored within the computer system.

DHS may conduct these activities in any manner without further notice. By clicking OK below or by using this system, you consent to the terms set forth in this notice.
The highlight is mine. Does this mean that in order to go to the US I must allow the US government to hack my computer?
The other good bit is that the dialogue only has an OK button, you can't even cancel and get out.
I just thought "you can't do that" then suddenly remembered what the response will be "yes we can".
