I haven't seen cases of this nature, but I'll say this. The essence of what the law currently allows is to collect a lot of information in the name of border safety. The possibility of criminals, hackers, and so on is a relevant consideration. I don't want to exaggerate the nature of the problem, but the more information the government collects, obviously, the more it's at risk of being collected and hacked by people with criminal intent. That, I think, is another reason that government should be careful not to collect information beyond what is necessary, and even if it is necessary, not to retain it beyond the period necessary to keep it. The government is obviously a repository of a lot of very interesting information that is of interest to people with criminal intent.
