<p style="margin: 0px 0px 15px;">UK police are lobbying the
government to be given access to every UK Internet user's Web
browsing history as part of the new Snooper's Charter—the
Investigatory Powers Bill—which is expected to be published
next week. According to<span class="Apple-converted-space"> </span><i>The

Liberal Democrats when they were part of the previous

<p style="margin: 0px 0px 15px;">Richard Berry, the National
Police Chiefs’ Council spokesman for data communications, is
quoted as saying: "We essentially need the ‘who, where, when
and what’ of any communication"—who initiated it, where were
they and when did it happened. And a little bit of the ‘what’,
were they on Facebook, or a banking site, or an illegal
child-abuse image-sharing website?"</p>

<p style="margin: 0px; line-height: 14px;">Edward Snowden
takes to Twitter to mock UK's contradictory statements.</p>
</div>
</aside>
<p style="margin: 0px 0px 15px;">According to<span
class="Apple-converted-space"> </span><i>The Guardian</i>,
Berry accepted that it was "far too intrusive" for police to
be able to access the content of online searches and social
media messaging without additional controls—for example, by
requiring a warrant signed by a judge.</p>
<p style="margin: 0px 0px 15px;">One of the problems with the
idea of allowing police access to somebody's Web browsing
history for the previous year is that, taken in aggregate,
that information gives a very detailed picture of a person's
life, and is thus just as intrusive as viewing online searches
or social media messages. Another issue is that it is easy to
circumvent this kind of snooping by using<span
class="Apple-converted-space"> </span><a
href="https://www.torproject.org/" style="text-decoration:
none; color: rgb(105, 159, 179);">Tor</a><span
class="Apple-converted-space"> </span>or a VPN, both of
which would obfuscate your behaviour enough that your ISP
can't track you.</p>
<p style="margin: 0px 0px 15px;">The move by the police seems to
be part of a larger campaign by the UK's security apparatus to
push for the<span class="Apple-converted-space"> </span><a

style="text-decoration: none; color: rgb(105, 159, 179);">increased
online surveillance</a>, which they like to frame as
"merely" retaining capabilities they enjoyed when
communications were analogue. Although it is true that the
fraction of messages that they can track has gone down in
recent years, this overlooks the fact that the overall volume
of communications has gone up even more substantially, which
outweighs any percentage loss.</p>
