No, this is not &quot;just&quot; providing a mechanism to enforce that law.  They&#x27;re creating a permanent record of every individual&#x27;s travels, regardless of whether they&#x27;re wanted for any crimes, and they are storing it indefinitely.<p>If you don&#x27;t understand why that&#x27;s a bad thing, and why intelligent people are freaked out about it, I strongly suggest you study history.
