Whenever someone suggests it's OK for the police to arrest people for future crime they haven't committed I feel the need to point out that the police do not always act in the public interest. Individuals abuse their powers.

e.g. when they do things like holding illegal employment blacklist[1][2][3] of innocent people.

I don't want to live in a country where, for example, the police can punish you just because they don't like trade unions.

What's I find ironic is that all this police state bullshit never seems to actually deal with antisocial behaviour or low level crime, it's always for political infractions.

We have more CCTV in London than almost anywhere else on the planet and you still get harassed outside tube stations by organised gangs of soliciting very forcefully for "charity" collections.
