Is 4chan the perfect Pirate Bay poster child to justify wider UK site-blocking?

I genuinely do not understand where how the idea of building a total surveillance police state, where all speech is monitored, can even as much as seriously be considered by an allegedly pro-democracy, pro-human rights government, much less make it into law.

Also:

Step 1: Build mass surveillance to prevent the 'bad guys' from coming into political power (its ok, we're the good guys).

Step 2: Your political opponents capitalize on your genuinely horrific overreach, and legitimize themselves in the eyes of the public as fighting against tyranny (unfortunately for you they do have a point). They promise to dismantle the system if coming to power.

Step 3: They get elected.

Step 4: They don't dismantle the system, now the people you planned to use the system against are using it against you.

Sounds brilliant, lets do this.

Politicians represent the country, if politicians are corrupted and stupid then the country is corrupted and stupid

That's assuming voting systems or checks and balances don't matter. If you made structural mistakes in how you choose politicians, you're going to have a worse time than if you use better systems.

The people will always get the politicians they deserve.
